Toll lanes around the Capital Beltway and I-270 in Maryland could be built in several separate phases and even operated by different companies under the latest plans released to industry insiders. It indicates Beltway construction could last for years.
The first phase would include fixes for the Legion Bridge.

A new document sent last week ahead of the next forum for private companies that could design, build and operate the lanes said that while Maryland eventually plans more than 70 miles of toll lanes from Frederick to Bethesda and from the Legion Bridge to near Oxon Hill, building out the entire network could take many years.

In addition to the already disclosed deferral of any toll lane construction on Interstate 270 north of the Shady Grove Metro, the new documents indicate that the rest of the toll lanes would be divided into entirely separate phases that could be awarded to entirely separate contractors.

To start, Maryland would only award a contract for toll lanes across a reconstructed or rehabilitated American Legion Bridge extending some to-be-determined distance into Maryland (Virginia is separately set to extend the 495 Express Lanes to just shy of the Legion Bridge to connect).

The private company or companies that would design, build and operate Maryland’s toll lanes would remain responsible for the toll lanes maintenance and upkeep for 50 years, but would not be responsible for any maintenance of the Legion Bridge or the regular travel lanes.

Overall, that first phase contract would be expected to cost $2 billion to $5 billion for construction and design, the Maryland document said.

One potential bidder, Cintra and Ferrovial Agroman, suggested about a year ago that a segment over the Legion Bridge should include the proposed toll lanes up the I-270 spur to Shady Grove, with another segment for separate bids to cover the Beltway from the I-270 spur to U.S. 50 in Lanham. That private group, which is building the Interstate 66 toll lanes outside the Beltway in Virginia, believes those would be the most profitable segments, and toll lanes south of U.S. 50 past Branch Ave. near Joint Base Andrews would make less money.

It is not yet clear whether that segment in Prince George’s County is the one Maryland plans to build last.

Hope for “shockingly innovative” approach
For the initial projects, Maryland’s stated goals are congestion relief when the project opens, minimized impacts when possible during four to five years of major construction on each segment, a split of toll payments with state or a single upfront payment to state and accelerated delivery.

“In meeting MDOT’s goals, MDOT is looking for a partner with shockingly innovative approaches that will provide high value with a focus on ensuring excellent customer service to MDOT and the public,” the message to the industry said.

An outline of the public-private partnership agreement would be released this winter, and the state’s Board of Public Works would approve the continuation of the procurement process in February.

Final details of what the state is looking for in an initial project are now expected in early 2020, with bids due by summer 2020.

Maryland hopes to select a winning bidder and close the deal by the end of 2020, which could allow construction to start on a first segment of toll lanes as soon as 2021.

Of course a NEPA EIS/location process study and document needs to be completed first. 

I wonder what would be the feasibility for constructing the above to a 12-lane design like the I-495 HOT lanes in Virginia?  At least to the I-270 split.  Given the right-of-way constraints in Maryland.

Definitely won't be easy. Will be interesting to see what "shockingly innovative" approaches the private companies come up with. My guess is that most will have the toll lanes built partially underground.

I just reviewed Google Maps aerial again.  Looks like ample space for a 12-lane design like the I-495 HOT lanes in Virginia, with at most 20 residential acquisitions.

The soundwalls are back pretty far from the travel lanes along this stretch. I'm not even sure any complete properties would need to be taken (unless the design requires hard barriers with extra shoulders, not just rubber bollards, between the roadways). One of the few tidbits of info I learned at the July workshop was that they were concerned about driver confusion with potentially changing rules for the lanes as drivers traveled north from Tyson's Corner-that seemed to be an argument for keeping the NoVa setup at least up to the 270 spur. The Old Georgetown Rd stretch (between the 270's) would be an ideal point to break up the Express lane standards.

CPZ had an interesting point above about MDTA's bond status possibly affecting plans to allow HOVs in the new lanes-it's not something I've read elsewhere, but at this point the local media is basically just reporting press releases.

There is an 84" WSSC fresh water pipe that was tunneled under the beltway (https://www.wsscwater.com/contents/news/2015/wssc-completes-10-year-long-bi-c.html) for 5.3 miles starting at Connecticut Ave. It's between 90' and 280' below the surface, and was bored thru bedrock. I don't recall any specific plans that the new lanes would need to interchange with all existing cross roads. Perhaps a truly express (bored) tunnel from the vicinity of 495/270/355 to 495/95 would be "shockingly innovative"?

Montgomery County Planning Department is working on plans to overhaul the Ga Ave interchange (https://bethesdamagazine.com/bethesda-beat/development/county-planning-department-unveils-preliminary-plans-for-reconfiguring-georgia-avenue/). SHA is reportedly working on plans to realign Ga Ave in this area, including wiping out the reversible lane. Maybe these 2 groups should sit down with those working on plans for new interstate lanes before they piss away too much money planning/building things that will only last for a few years.

It's important to keep the same standard for managed lanes that directly connect.  Beltway lanes should allow hov for free.  We saw very clearly the problems on 395 with different standards as you cross into Arlington with hov only lanes and south of there allowing toll customers but requiring all to have ez pass.  Let's not make the same mistake again.

I-66 allowing two people to ride free is a good example, too—someone who falls in that category who exits onto the Beltway HO/T lanes has to remember to flip the switch on the E-ZPass Flex while going down the ramp to the Beltway (I have done this a number of times and it's no big deal, even with the E-ZPass mounted on the passenger's side of the rearview assembly, but you do have to remember to do it). Of course that issue is scheduled to go away when the I-66 HO/T lanes open outside the Beltway, as VDOT plans to change the free ride to HOV-3 at that time for consistency.

Switching between two highways is theoretically less of a problem than continuing straight on the same main line, even if crossing the county or state boundary.  But I agree that it would be a lot easier if there were consistent rules on all managed lanes in the area.

I-66 inside the Beltway is a unique problem because there is no non-managed option.  The other highways provide free lanes for those who don't carpool or want to pay the toll.  For I-66, your option is to travel outisde of rush or to take an alternative routing.

California has a bunch of toll roads with different rules for HOV-2 and HOV-3+.  (I believe that during off-peak hours HOV-2 can ride free on I-10 but HOV-3+ can ride free during rush hours.  There may also be some roads that offer a carpooling discount for HOV-2 and a free ride for HOV-3+.)  For this reason the Fastrak Flex has a 1-2-3 switch that you basically set for the number of occupants and don't have to change in the middle of driving.
