I-30 Canyon Project(Dallas)

[bwana39]

I noticed that I35E SB Traffic headed towards I30 EB still have to merge one or two lanes to across traffic. But still better than the current situation right now which is 2 lane traffic funneled down into one lane exit.

Is this due to construction? I have not been through the upper mixmaster southbound in years. GSV and my memory show a 2 lane exit that remains 2-laned. There is that weird flyover that you can take that is an extra lane, but used to be one of the two available, but it is not really significant to this process.

Nope is a 2 lane traffic funneled down to one lane entrance to I-30 EB. Check this link out.

The Dallas Morning News has a report about the massive cost overrun for this project.

I-30 Canyon costs balloon by another $196 million
The price tag has nearly tripled since the project's proposal in 2019.

More than five years after the redesign of a depressed roadway on Interstate 30 that separates downtown Dallas and the Cedars was proposed by the Texas Department of Transportation, project costs have nearly tripled, growing to almost $890 million.

The agency first went public with plans for the below-grade roadway between Interstate 35 and Interstate 45, known as the Canyon, in 2019. Part of TxDOT's plan to stitch together South Dallas with downtown, the project was projected to cost $300 million — but inflation has pushed costs up, according to agency officials.

Members of the North Central Texas Council of Governments' Regional Transportation Council on Thursday approved a plan for another $196 million in costs, with TxDOT and the council each contributing $98 million.

The project will reconstruct and widen the roadway to six freeway lanes for both westbound and eastbound directions. It also consolidates several ramps in an effort to improve traffic flow, reconstructs the high-occupancy vehicle lane and adds the supporting deck walls needed for a future deck plaza over I-30.

Construction on the project was expected to begin in 2022 but hasn't broken ground as higher costs and slowdowns in funding availability led to delays, TxDOT spokesperson Tony Hartzel said.

Motorists can expect to see work on the I-30 Canyon begin in early 2026, though material fabrication has already started, Hartzel said. Traffic flow will be maintained throughout construction, which is expected to last five years.

I'm surprised it isn't over a billion dollars. Though i'm no engineer after seeing the plans for this project, it still seems like a good deal.

I was hoping construction would start late 2025 not in 2026. But either way I thought it was gonna take less time like around 4 or 3 years since is not even a full mile of roadway. Will be interesting how will it progress. If it ends around 2031 by that time some projects nearby probably already started like the I-30 East Dallas Project, Western US 80 full reconstruction project, I-30 Operational Improvements in Garland Texas.
