The 3.3-mile project to widen I-30 in Dallas-Fort Worth is scheduled to begin in July, according to a state filing.

With an estimated construction cost of $250 million, the interstate will be widened from four lanes to include three travel lanes in each direction between Linkcrest Drive and I-820 in Tarrant County.

“The proposed improvements would include … one-way frontage roads with pedestrian and bicycle facilities for approximately 3.3 miles,” a Texas Department of Transportation (TxDOT) document shows. “The I-30 interchanges at RM 2871 and Spur 580 would be reconstructed. U-turns would be provided at Linkcrest Drive and Chapel Creek Boulevard.”

Alameda Street, the I-820 frontage roads between Westpoint Boulevard and North Normandale Street and the connector from southbound I-820 to westbound I-30 would be rebuilt. The project is set to begin in July and take four years to complete.

It “would provide 18 feet and 6 inches of vertical clearance for Freight Mobility Corridors,” according to the TxDOT document. “New denial of access would be required along the frontage roads from adjacent properties at new ramp junctions.”

The Linkcrest to I-820 widening is part of TxDOT’s larger I-30 corridor improvements. Those include the segments between I-820 and Chisholm Trail Parkway; I-30 from I-820 to Camp Bowie Boulevard; U.S. 287 to Cooper Street; and Cooper Street to State Highway 161.

“The purpose of the I-30 West Corridor Study was to evaluate the reconstruction and widening of the existing I-30 corridor, consider potential express lanes, evaluate improvements to the frontage roads, ramps, and cross streets including the I-30/I-820, I-30/Spur 341, and I-30/SH 183 interchanges within the project limits and add shared-use paths along the project for improved bicycle and pedestrian accommodations,” reads the website for the project.
