Title: Bridges replaced directly next to the old one
Post by: fillup420 on September 29, 2019, 08:05:41 AM
North Carolina seems to have a thing for this. I drove up NC 49 the other day and noticed NCDOT had replaced a small creek bridge by building it next to the old one, and then slightly rerouting the roadway. to me it seems like an overkill way to replace a bridge. yall know of any more examples like this?

Well, there's the Tappan Zee outside New York City, the Pont Samuel-de Champlain in Montréal....

It's a fairly common tactic, I think.

I'd guess it's usually done to avoid the lengthy detours of a total road closure.

Or the bridge is retained for historical significance or recreational value.  When MDOT constructed the current US-12 bridge over the St. Joseph River in Mottville MI, it kept the previous narrow camelback bridge and the old highway alignment west of it was made into a small park.

Yep, this is done quite often.  When the roadway is slightly shifted to the new bridge, it can often be done so that most motorists aren't even aware of the slight shift.

For smaller overpasses, most of the NJ Turnpike overpasses that have been rebuilt were rebuilt right next to the original bridge, sometimes within a foot of the old bridge.

It's also common to build half of the new bridge just slightly off the current alignment.  When the old bridge is demolished, the remaining half of the new bridge is built in the vicinity of the old bridge.  Such is going on here at an old lift-bridge on US 130 in NJ: https://goo.gl/maps/teBqz8PkcSmJGuTp8 .  The lift bridge formerly held 4 lanes, no shoulders. The new SB overpass has been built here right next to the lift bridge and currently is hosting one lane per direction.  You can see the new bridge supports going up right where the lift bridge is located, which will eventually be for the Northbound lanes.  In the end, the new bridge will have 4 lanes and full shoulders.

This works well if the road is already somewhat curved. In my lifetime I've seen several bridges replaced in Arizona; the majority of them are on a straight stretch of road. The jog, while not hard to navigate, is pretty obvious. This tends to be amplified due to the fact that the newer bridges tend to have wider decks to accommodate more lanes, shoulders, sidewalks and other safety features. .

I-10 over Escambia Bay outside of Pensacola, FL; also I-10 over Lake Pontchartrain outside of New Orleans, LA.

The shift is quite noticeable on both examples.

Three bridge replacements in the last decade in the Bay Area have had this happen:

- the Treasure Island-Oakland portion of the Bay Bridge
- the southbound lanes of the Carquinez Bridge
- the northbound lanes of the Benicia Bridge

If I'm not mistaken, the same thing happened with the Dumbarton Bridge in the 1980s

Yeah, this is definitely quite common. Still interesting!

A relatively cool example near me would be the McMillin Bridge (a concrete half-through truss bridge), along WA-162 between Sumner and Orting. The old bridge was wearing out quickly, but was on the register of historic places. They built a new bridge alongside the old one, rerouted the highway onto the new bridge (complete with a new curve in the highway), and left the old one exactly where it had been for about 70-ish years. It was designed by Homer Hadley, designer of the original US-10 Lake Washington Floating Bridge (sunk in 1990).

That jog when this happens on sufficiently straight roads is annoying.  Here's a local example (https://www.google.com/maps/@42.7801105,-73.6963742,3a,36y,196.62h,86.95t/data=!3m7!1e1!3m5!1sXR7NpOaoh26XhcpOpX5imQ!2e0!6s%2F%2Fgeo0.ggpht.com%2Fcbk%3Fpanoid%3DXR7NpOaoh26XhcpOpX5imQ%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D253.65137%26pitch%3D0%26thumbfov%3D100!7i13312!8i6656).  Meanwhile, there are other cases like NY 441 over I-490 where it's not even possible to tell that the old bridge was next to the new one unless you remember the construction.

Reminds me of a similar situation on NY 5S (https://www.google.com/maps/@42.9341309,-74.2843328,3a,24.9y,41.86h,83.98t/data=!3m6!1e1!3m4!1sfoNZDWYhHhK9AJt0CrEcRQ!2e0!7i13312!8i6656).  One bridge is an old rail bridge (and, currently, the road, though not in the street view), the other has the Erie Canal Trail.  Which one has the road and which one the trail seems to periodically be swapped.  The southern (former road, current trail) bridge was actually a temporary section of Thruway when the Thruway bridges over Schoharie Creek were washed out.

Wow that's a pretty sharp shift in alignment! I'd be worried about getting into a head-on collision with someone who isn't paying attention.

The bridge down the road from my house has a fairly pretty obvious jog, made more obvious by the deviation from the straight path of the power lines and irrigation ditch, nonetheless easy to navigate:
https://goo.gl/maps/BWg5fDoEEyrWuF4w7

About a half hour west of me, ADOT replaced a bridge on US 70 about 10 years ago near Bylas. Approaching from the east, the road is straight, and the jog is obvious. From the west, the road makes a turn, and the approach was tied in seamlessly to the curve in the road:

Another example: while the new Seaway Bridge is mostly tied in like it was always there, there is a very noticeable jog (https://www.google.com/maps/@45.009457,-74.7394772,3a,75y,30.56h,93.51t/data=!3m6!1e1!3m4!1suxDE-SxsNt2OQlAQjpE6Mg!2e0!7i13312!8i6656) at the toll plaza, which was built adjacent to one of the piers for the original bridge.

hmmm so it seems this is very common. I guess NCDOT didn't do a very good job because the roadway shift was quite noticeable, and they placed s-turn warning signs on either side.

It's not that they didn't do a good job, but as shown above sometimes there's not much choice.

The new SR 520 Floating Bridge in Seattle actually got rid of a jog in the original bridge on the west end. You can see the old bridge at right making an extra swoop coming off the original approach structure.

In Branson (MO), when they replaced the Taneycomo bridge, they left the old one up and open to traffic.  The new one serves Branson Landing directly, while the old one (previously/still US-65-Bus) skirts around the edge of that district.  Aerial view here.

The M-104 drawbridge between Spring Lake and Ferrysburg was replaced in the mid-60's with a high bridge on a parallel line to the south.  Savidge St was reconstructed to the south, and a stub of old Savidge St remains to access the properties on the old bridge approach.

New I-5 bridges in Tacoma over the Puyallup River, which actually straightens the freeway a bit by moving the bridge. Shown here is construction of the northbound bridge which is now complete. Currently both directions of mainline traffic are routed on the new northbound bridge while the old northbound bridge is demolished and the new southbound bridge is being built. Currently the old southbound bridge is also being used for traffic headed to the exit just on the other side of the river (Exit 135 to SR167 and Portland Ave), shown near the top of this photo.

Totally forgot about this one!

Here's a diagram showing the current traffic movements. You can stay on I-5 using the old bridge, though it's signed as an "exit only" (it's really just a C/D lane).

Back in 1988-89 the I-5 dual (2+2) truss bridges over Cottonwood Creek and the UP RR tracks at Cottonwood, CA (between Red Bluff and Redding), which were separated by about 80 feet, were replaced by a single bridge, also 2+2, but with a K-rail down the middle.  This new structure was located in the former median between the two original bridges.  The rationale behind the replacement -- although the original bridges were only 24 years old at the time -- was that the combination of winter rains and extreme summer heat in the area had created fissures in the concrete around the bolts holding the structure to its anchorages, and at least one of the bridges had started to laterally shift as a result.  Those original bridges were notable as the only through truss bridges on I-5 in CA; the only other similar structure on that route, the deck truss (actual pavement running along the truss top) over the Sacramento River arm of Lake Shasta, was itself replaced a year or so ago.

Sometime in the 1960's they constructed a parallel 2-lane span for eastbound traffic, leaving the old arch in service for westbound traffic. After US 20 was moved to the bypass in 1988, ODOT replaced the newer 2-lane span with the current 4-lane span and took the rainbow arch out of service prior to relinquishing the old highway to Lorain County.

There's a similar bridge, also out of service, parallel to I-75 just north of Eagleville Road (Exit 168).  I'm guessing this was the original US-25 routing before the freeway was built:

Camel-back bridge near Nunica MI that is right next to I-96: https://www.google.com/maps/@43.0745769,-86.0521176,3a,75y,255.98h,94.24t/data=!3m6!1e1!3m4!1shqCj-ViUI8VgsUrJNU9-kA!2e0!7i16384!8i8192?hl=en

I'd guess this used to be US-16 (and maybe M-16 before that).

As kids we liked seeing this bridge because it meant we were nearing the beach in Grand Haven.

In the Long Beach, CA harbor area, Ocean Blvd. crosses the Cerritos Channel on the Gerald Desmond bridge, to connect Terminal Island to Long Beach.  This section of road is not currently signed though in Wikipedia it is shown as a section of I-710.  The new Gerald Desmond bridge may carry the I-710 designation; I'm not sure.  It is scheduled to open within a year.   These pics show:
(1) The new and old bridges (facing east), and

(2) The construction bypass on the east side of the Cerritos Channel where the new bridge will have an elevated connector to the I-710.
Note the blocked westbound lanes have a sign directing travelers to CA-47 [just below the traffic light near center of photo].

Here (https://goo.gl/maps/e2raNn2eM63y5o1D6) is my favorite example of this. The service road was US 66, and used the arch bridge. Then, the interstate got built, and, if you look at both the bridges, it looks like the interstate used to use the arch bridge, because the 2 highway bridges were not built at the same time, made obvious by the structural differences. The service road then used the arch bridge until it too was replaced, the bridge the service road is on being the newest. Maybe someone from the area will correct me, but I believe that is how that went.

So there you go, 4 different bridges, built right next to each other, all at different times.

The Truss (not arch) bridge carried traffic until 1997 when the new bridge to the north was built.

The Eastbound 40 bridge was replaced recently: https://www.abqjournal.com/31126/breaking-partial-collapse-reported-on-i-40-bridge-at-rio-puerco-exit.htm

This shows the original Greenspot Road bridge across the Santa Ana River in East Highlands, CA (San Bernardino County).  This is not a numbered highway; these pictures are from December 2011.  Since that time, the bridge was replaced by a modern concrete structure downriver.  That is the Seven Oaks Dam in the distance.

The original 11th Street bridge carried US66 for many years.  The two I-244 bridges were added in the 70's. The 'new' 11th Street bridge was built in the 80's and the original was left as an architectural example.

The original intent was to use it as a combination ped/bike crossing but it is on the wrong side of the new bridge. There is a nice plaza at the north end but there is a large wrought iron fence that appears to fully block access.

Apparently the Rio Dell Bridge on US 101 was built alongside its predecessor circa 1941.  The previous bridge opened in 1914 as part of the Redwood Highway and was condemned once it was replaced.

There are a couple of bridges on US 40 in Duchesne County, Utah that were built in 1959 right next to the original bridge:

The old bridges are now closed to traffic, but they're still there and are some of the oldest road structures still standing in Utah. They probably date to the late 1920s.

The I-280 Veterans Glass City Skyway bridge over the Maumee River in Toledo OH was built next to the Craig Memorial Bridge (drawbridge).  The latter is still in use as a surface street and OH-65 was extended south along it to a relocated connection to I-280.

I'm surprised nobody has mentioned the replacement for the Governor Harry W. Nice Memorial Bridge.

On a much smaller subject. I read that the Dutchess County Road 26 Bridge over the Metro-North Harlem Line at the site of former Dover Furnace New York Central Railroad station was a 2013 replacement bridge along the same alignment (http://bridgereports.com/1392142) as the older one. However, in every photo I've ever seen of that former station site, two abutments for a much older bridge can be seen.

I'm highly surprised nobody has mentioned the Sunshine Skyway Bridge over Tampa Bay in Florida (or maybe I missed it).  Anyhoo, when I first saw it around Christmas 1989, there were still remnants of the original bridge (replaced because of a tanker vs. bridge collision in 1980 that killed about 35 people), so it was kind of, well, weird seeing the original-it probably would have scared me more than the current bridge might.  Some of those remnants have been refashioned into fishing piers.  You can see pictures of old next to new in Wikipedia.

The old "Green Bridge" over the Kanawha River on I-64 in Putnam County, West Virginia now has its main span removed.  I was amazed how close the new structure is to the old structure.  Locals named the old bridge the "Stinky Bridge", as a reference to the small chemical plant in Nitro next to the Interstate that stored Mercaptan, the main additive to natural gas.  Didn't take much of that to "raise a stink".

SR 38 in Oregon had the Scottsburg Bridge replaced with one built adjacent to it. This allowed for a sharp curve on the north end to be smoothed out considerably.  Unique feature: The new bridge has lighted concrete pylons on each end to let motorists know they are present when visual conditions are not at their best.

Yep, this is done quite often.  When the roadway is slightly shifted to the new bridge, it can often be done so that most motorists aren't even aware of the slight shift.

This works well if the road is already somewhat curved. In my lifetime I've seen several bridges replaced in Arizona; the majority of them are on a straight stretch of road. The jog, while not hard to navigate, is pretty obvious. This tends to be amplified due to the fact that the newer bridges tend to have wider decks to accommodate more lanes, shoulders, sidewalks and other safety features. .

However, by the time a third bridge is needed to replace the second, it can often go back on or near the original alignment, straightening things out again. The IL 178 Bridge in North Utica IL is an example of this.
