Commuters in Oak Hill are seeing a transformed interchange after the Texas Department of Transportation finished the long-awaited Oak Hill Parkway project. The reconstruction aims to resolve decades-old traffic bottlenecks at the intersection of US 290 and SH 71.
Why it matters
The upgrade replaces an outdated Y-configuration interchange with a single-point urban design, intended to finally address traffic capacity issues that have plagued the area since 1995. These changes are designed to improve safety and connectivity for local residents navigating the corridor.
The $677 million infrastructure project replaces a layout that reached capacity in 1995 with modern flyovers and improved mainlanes. The work includes 14 miles of shared-use paths and 1.5 miles of sidewalks, though exact reductions in peak commute times remain to be tracked.
The players
Texas Department of Transportation
The state agency responsible for managing highway infrastructure and the Oak Hill Parkway construction.
Colorado River Constructors
The private contractor responsible for the construction of the parkway.
The details
Colorado River Constructors carried out the build, which began in 2021 after the contract was awarded in 2020. The redesign swaps the old Y-configuration for a single-point urban interchange and adds nonstop mainlanes to streamline traffic. The project recently received the 2026 Environmental Excellent Award for its public involvement and education efforts.

The Texas Context
This project finally addresses the congestion capacity thresholds that were first officially documented for this corridor back in 1995. It marks the conclusion of a 30-year planning and development cycle aimed at modernizing aging suburban transit links.
Drivers in Oak Hill should expect improved traffic flow through the new US 290 and SH 71 interchange now that construction is finished. Residents can also begin utilizing the 14 miles of new shared-use paths and 1.5 miles of sidewalks added throughout the project area.
The takeaway
The project provides a significant redesign to one of the city's most congested intersections to improve long-term safety. Local commuters should monitor daily traffic patterns over the coming months to see how the new flyovers and interchange layout affect their regular routes.
