I have seen that starting late in 2021, the 60 year old crossing between Boone and Cooper Counties will undergo a lengthy replacement project.

Will this new bridge have additional traffic lanes added to it? Given how narrow the existing bridge is (https://www.google.com/maps/@38.959185,-92.5458115,3a,75y,57.75h,77.2t/data=!3m7!1e1!3m5!1s-iWSVkTVDBI8qd13sV9fqQ!2e0!6s%2F%2Fgeo3.ggpht.com%2Fcbk%3Fpanoid%3D-iWSVkTVDBI8qd13sV9fqQ%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D122.17828%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192), I think the new bridge should have full 10 ft. shoulders on both sides of the traffic lanes in both directions.
What are the current requirements for new-construction bridges? Are they still allowed to have inadequate shoulders? I can't remember.

Kind of bittersweet because, in my opinion, that bridge is the highlight of driving I-70 across Missouri.

Design won't be seen until June/July 2021 timeframe when the design/build proposals are unsealed.
Hopefully they will make the bridge architecturally significant. Design/Build typically is a rush to the lowest common denominator in bridge design. (read: low cost, boring)

MoDOT Moves Ones Step Closer to Building a New I-70 Rocheport Bridge
JEFFERSON CITY — Following an extensive evaluation process, four qualified teams have been selected to compete for the contract to design and construct a new Missouri River Bridge on Interstate 70 near Rocheport.
The Missouri Department of Transportation has received Statements of Qualification from potential design-build teams for the Rocheport Bridge project.
"We are very pleased with the interest we received in working on the Rocheport Bridge project. The four short-listed teams are all very experienced and capable of producing a successful project," said Project Director Brandi Baldwin. "We look forward to moving forward in the process and selecting the final design-build team."
The following teams (in no particular order) were selected to further develop their proposals on the project:
- Traylor-Ames Joint Venture Team - Traylor Brothers, Inc.; Jacobs Engineering Group, Inc.; Ames Construction, Inc.
- American Bridge/Garver Team - American Bridge Company; Garver, LLC; Hg Consult, Inc.; Terracon
- Rocheport Bridge Constructors - Massman Construction Company; HNTB Corporation; Emery Sapp & Sons, Inc.
- Lunda Team - Lunda Construction Co.; Parsons Transportation Group, Inc.; Dan Brown & Associates; Hugh Zeng United
There are still opportunities for additional consultants and subcontracting firms to be added to each team. A networking opportunity for Disadvantaged Business Enterprises will be offered this spring.
Design-build projects combine both the design and construction phases into one contract. The selected team completes the design and construction in parallel instead of in succession. MoDOT provides the project goals, budget and schedule, and the contractor team conducts the work. This technique has been known to significantly save time and money. For more information about design-build or to see other similar project across the state, visit www.modot.org/design-build-information
This $240 million project was made possible by the July 2019 award of a $81.2 million Infrastructure for Rebuilding America (INFRA) grant from the U.S. Department of Transportation. The project will replace the existing I-70 bridge as well as reconstruct the Route BB interchange just east of the bridge.
MoDOT has established design-build goals for the project. The contractor team will be selected using an apparent best-value process to determine the team who can best meet or beat the goals. To view the full list of goals and project timeline visit www.modot.org/RocheportBridge.
MoDOT will issue the request for proposal later this month. Proposals will be due in June and the design-build team is expected to be selected in July, with construction beginning as early as later this year with completion by the end of 2024.

It should be built with 4 12' lanes (2x2) with 10' outer shoulders and either 4 or 6' inner shoulders. They might opt for 3x3 biut the shoulders should remain at 10' and 4 or 6'.

MODOT still has a long term goal of widening I-70 either by making it at least six lanes across the state or a separate parallel truck highway of some sort. I think the parallel highway for trucks would be an insane waste of money and land. OTOH, six lanes across the state is both realistic and something that MODOT should be actively working, even if it's one short stretch rebuilt at a time. One stretch would be the Missouri River crossing at Rocheport where building a six lane bridge (minimum) should be a required objective. Even better would be six lanes with the ability to widen it to eight lanes.

I can't see dedicated truck lanes across the state, but I could most definitely see some dedicated truck lanes where the grades are more challenging.
It would probably cost billions, but I-70 needs some flattening out in certain places. Too many up and downs. Not as bad as I-44 however.

Many parts of 44 subsumed the 4-lane US66 in part or in total, especially between Lebanon and Rolla where 66 had been built on a new alignment from the original. Since much of that was done in the 40's and 50's, it makes sense they didn't flatten it out more. OK has the same problem with the Turner Turnpike between OKC and Tulsa.

Thanks for the correction. Hmmm, shame. I thought that since the widened roadway to six lanes and came with an 80MPH speed limit they would have improved the grade changes.

I know MODOT isn't flush with cash but would have been cool to see a unique design like a suspension bridge or something to spruce up the boring drive from KC to STL.
^ Or something with a slightly longer main span and less piers in the river for barges to hit.

Just another example of where design-build equals BORING.
Utility & cheap wins out over a small level of aesthetic.
It definitely seems like one of the major interstates crossing the largest river in the country warrants a more unique bridge.

Design looks boring to me. Yawn.
It's better than the new EB US 40/61 Missouri River bridge still imo, as it's at least uniform in the Rocheport example. Was really hoping for MoDOT to replicate the truss design of the WB span (former EB) onto the new EB span, but nope, it's pretty much an elongated generic highway overpass.

From what I gather from my bridge engineer friend, truss bridges are white elephants. Nobody wants them because they're so costly to maintain.

Looks like that could be the case from how many truss bridges I've seen get replaced with something more elegant like cable-stayed, or something more boring like the proposed Rocheport bridge here. Kind of wondering why truss bridges were so popular and frequently used when the interstate system was built back in the 60s and even before that, and like the cloverleaf, how it fell out of fashion today.
If I remember correctly, engineers back then weren't sure if cable-stayed bridges were even appropriate for large spans such as major river crossings along Interstates. That development has been more recent.
The U.S. has been a little behind with the construction of cable-stayed bridges. Many river crossings in Europe were built with cable-stayed bridges from the mid-1960s onward. The Rocheport Bridge is a little older, completed in 1960 so it was designed a few years before cable-stayed bridges became more common for such spans.
The Rocheport Bridge has a main span of 550 ft. For example the Rhine Bridge in Leverkusen, Germany is a cable-stayed bridge built in 1965. It has a nearly 1,000 ft span.

The technology in pre-stressed pre-formed concrete beams has come a long way. They are preferred because they hold up longer than steel truss or sections, don't need to be painted, handle/absorb seismic and road stresses better and the biggest part is that they are extremely cheap to fabricate to spec.
The limitation is that they can't span certain distances and still maintain some of the above properties. This is where a steel beam usually takes its place. But it has to be painted, inspected often and doesn't absorb stress as well.
As for why trusses were once popular and aren't anymore, is really about weight relative to the steel cross section. To get a bridge to distribute its weight properly, you would either have to build enourmous steel sections which then requires a large support pylon for the weight, or use a weaker steel and spread the stress more equally, which allows pylons that are smaller.
Today, steel is much stronger, but trusses require joints to flex those stresses. Those joints rust, crack and fail and need to be replaced. That explains the desire to move to cable stayed concrete.

After this it should be fairly simply to widen the rest of the interstate to 6 lanes between STL and KC, no?

Assuming the infrastructure bill passes the House, I don't know if they will get enough to widen across the whole state but hopefully they will widen some sections with that money.
In my opinion, they should probably start at Wentzville and work their way westward. Hopefully they can do some of the trickier sections (like the railroad bridge between exits 208 and 209) first.

Wentzville is one of the tougher sections to widen I-70 for six lanes. A railroad viaduct would need to be rebuilt and there are some frontage roads built right up to the interstate. Wentzville and Columbia may be the last sections of I-70 widened from four lanes to six. It would be better and easier to just start six-laning the rest of I-70 in spurts starting from the new bridge and east from KC and wait for the voter demand to widen the remainder.
Is Modot going to have to widen that cut through the bluffs on the east side of the river?

Thanks for the info. That at least takes care of the railroad viaduct. Additional lanes west of Wentzville Parkway would probably need to be added in the median with a Jersey barrier down the middle because of the adjacent frontage roads. Widening I-70 through Columbia will still be a bear though.

June 2023 Construction update:
Westbound traffic is on the new WB bridge. Eastbound traffic is expected to be switched onto the new WB traffic July 6th or thereabouts
Then demolition can begin on the old bridge so the new EB bridge can be constructed at that location
The Route BB/Roby Farm Rd overpass of I-70 has been demolished with the replacement coming in 3-4 months, per the director in the video

Has MoDOT announced if the old bridge will be imploded or dismantled during demolition?

I-70 traffic on Rocheport Bridge to be redirected Thursday evening (https://abc17news.com/top-stories/2023/07/06/i-70-traffic-on-rocheport-bridge-to-be-redirected-thursday-evening/)

ROCHEPORT, Mo (KMIZ)
Beginning at 7 p.m. on Thursday evening, MoDOT will begin to redirect traffic heading eastbound on the Rocheport Bridge to the new bridge.
Workers will narrow eastbound traffic to one lane and redirect it to the new bridge, with two westbound lanes and two eastbound lanes. MoDOT says by midnight, all eastbound traffic is expected to use the new bridge.
According to MoDOT the Rocheport Bridge carries 34,000 vehicles and over 8,000 commercial vehicles daily.
The redirection of traffic marks the start of the next phase of the project which entails demolition of the old Rocheport Bridge and construction of the new eastbound bridge. <-- For those who asked
As the shift occurs, MoDOT is asking drivers to pay attention, obey all traffic signs and to move over while in the work zones.

So here it is...the old truss bridge that carried I-70 over the Missouri River at Rocheport will be imploded in September.

the new bridge doesn't have any type of special design or anything? it's just a standard concrete and steel beam bridge?

The shipping/barge channel under the new bridges is wider than the current. Is that not special enough?

Nope, it needs to be made of steel beams that form triangles above the roadway. Truss Bridges are cool, but...this location probably would warrant something a little more basic going forward. It looks like a spot that might have an issue with ice forming on anything above the roadway due to the valley.

I agree that standard steel beam and concrete bridges are boring, but let's be honest: This bridge is in the middle of nowhere (relatively speaking). It doesn't need to look cool. And yes, I'd prefer it to be more visually interesting.
What bothers me is when these types of bridges replace stylistic bridges in cities, such as the Buck O'Neil Bridge (formerly the Broadway Bridge) in Kansas City, which had a triple-arched truss structure and was part of the city's skyline when looking at it from the North, especially when viewed from the downtown airport. The new bridge is taller but it's just concrete and painted steel beams with no visually interesting structure. The Heart of America Bridge, a mile to its east and which was a replacement for the upper deck of the ASB Bridge, is also visually uninteresting.
At least the Christopher S Bond Bridge is cable-stayed. It replaced the suspension-based Paseo Bridge.

There are a couple of reasons why the new bridge is a continuous girder bridge, and why we've been getting away from truss designs in new bridge construction more broadly. First, truss bridges are considered "fracture critical," meaning they lack any sort of structural redundancy. "Fracture critical" means that if one element of the bridge fails, the entire bridge will likely come down. The 2007 collapse of the I-35W bridge in Minneapolis was a classic example that demonstrates the "fracture critical" nature of truss bridges, and why new bridges are typically not designed as such.
Secondly, a through-truss design in particular, creates a limit to the size of a load that can be carried over the bridge, meaning that over-dimension (width and height) loads could not use the bridge and would be subject to a potentially-long detour to a suitable crossing that could accommodate the load's dimensions.
And so you end up with a design that can accommodate over-dimension loads and has built in redundancy for greater structural integrity.
Google Maps Street View has imagery from the new bridge as of last month:

The old Rocheport bridge is expected to be demolished around 7:30 AM tomorrow, September 10th. The demolition will be livestreamed here (https://www.modot.org/RocheportBridge). I-70 in that area will be closed from around 7-9 AM, with the KATY trail being closed until an all clear is called.

Edit: A nearby winery, for which the bridge can be viewed from, will be hosting a watch party where the public can see the demolition! https://www.instagram.com/p/Cw-tjJorWPw/ (https://www.instagram.com/p/Cw-tjJorWPw/)
The implosion of the old I-70 Rocheport Bridge was delayed for more than an hour due to fog. But once the fog cleared, the explosive charges went off and down she went! It was a spectacular sight to see.

I drove from Springfield to see the implosion of this bridge. 100+ people parked along Route BB to view the implosion from the blufftop at Les Bourgeois. I arrived just before 7, but the implosion did not occur until around 8:50. When the fog disappeared to reveal the bridge, the crowd burst in a round of applause and cheering. Spectators expressed disappointment as they continued to see traffic cross the new bridge, wondering when the old one will finally blow.
I got the whole thing on video. Three minutes prior to the implosion a warning blast was fired. I took it as a cue to roll the tape.
Waverly, Miami, Glasgow, Hermann, Washington, and now Rocheport... all lost over the past 20 years.. Which historic Missouri River crossing will we lose next?

The last GSV sweep shows the old bridge approaches being dismantled, yet the cantilever still in tact. It was only in August as well just a month or about before it's implosion.
R.I.P. bridge.
I thought the old bridge was neat. I liked the cantilever design. Sad to see it gone.
Before this bridge was built, you had to cross the Missouri at Boonville with US-40. There used to be traffic backups in Boonville waiting to cross.
