I-30 Canyon Project(Dallas)

(1/3) > >>

Plutonic Panda:
I feel like this project is large enough to warrant its own thread. I-30 will be widened, reconstructed, and realigned in some areas. This project seems somewhat similar to Denverís I-70 project. There will be potential for park caps in some areas though that wonít be initially constructed.

There was a public meeting earlier this year for the environmental clearance of the downtown canyon project. Link below includes schematics

The link below says "The project has an anticipated letting date in February 2024" which unfortunately is still three years away. Most TxDOT projects have been delayed due to Covid-related funding shortfalls.

There appears to be no organized opposition to the downtown canyon work. I'm thinking the bidding date could be advanced to be sooner if TxDOT's financial situation improves.

However, all work to the east has opposition and probably won't happen anytime soon, and by that I mean not in the 2020s. A new tactic used by anti-freeway interests in Houston and Dallas is to block right-of-way acquisition, which makes expansion impossible or much more expensive. The City of Dallas is trying to prevent any right-of-way acquisition on IH-30 east project.

My comment in April may be wrong. TxDOT has scheduled a public meeting for the first section of IH-30 east of IH-45.

--- Quote ---The proposed improvements would include ten general purpose lanes (five in each direction), two reversible managed lanes, discontinuous two to three lane frontage roads in each direction, and reconstruction of ramps and bridge structures. The proposed I-30 main lanes and managed lanes would be depressed from I-345/I-45 to Dolphin Road. Accommodations for bicycle and pedestrian travel along the project corridor are a component of project development.

The proposed Right of Way typically ranges from 308 to 505 feet in width. The proposed improvements would require additional ROW.

Observations

* The planned design remains 5-2M-5. (The freeway is currently 4-1M-4) So it appears TxDOT has worked out differences with the City of Dallas.
* Consistent with longstanding plans, the elevated lanes will be sunk below ground level.
* I think the frontage roads were originally planned to be continuous, but are now listed as discontinuous
* While the meeting announcement says additional ROW will be required, I'm expecting it to be minimal. Curtailing frontage roads will probably be the main way to reduce ROW requirements.

There were originally partial service roads in the canyon, they were mostly subsumed as exit lanes for the Horseshoe project. The service roads never had a lot of usage before they were repurposed.

There were a handful of exits and entrances, but they were awkward at best. As a quick point to make, Most of the roadway is 10 or more feet below ground level residing in a man-made canyon....therefore the name.

My belief is the convention center does as much or more to interrupt downtown to the south than I-30.
