Construction began Monday, May 9, 2016 on a $37 million overhaul of the US 75 interchange at President George Bush Turnpike.

The project, led by San Antonio-based Zachry Construction Corp., will reconfigure the ramps and merges at US 75 and Bush Turnpike, one of DFW’s busiest stretches of highway. The work includes an extension of the railroad bridge just north of PGBT, constructing new auxiliary lanes and rebuilding the Plano Parkway bridge spanning US 75.

TxDOT has an interactive map showing lane and ramp closure locations and dates along US 75, at www.drivetexas.org.  The map will open in a separate window, zoomed in to the US 75 project. You can click on various locations along the red line that shows the project extent, which will reveal detailed closure information. In the box on the right of that page, you can click back and forth between "Current" and "Future" to show present and planned closures.

Zachry Construction, which did the 2002 construction of the High Five, will start on Monday with work along the southbound frontage road between 15th Street and Plano Parkway.

“Working together with our partners from the City of Plano, City of Richardson, DART and NTTA, we are confident that this project will ease the congestion in that area,” said Kelly Selman, chief TxDOT engineer of the Dallas District. “It will ultimately cut down on the need for motorists to navigate tight merges to enter and exit US 75.”

Eventually, the existing retaining walls along US 75 in the vicinity of Plano Parkway will be pushed back, allowing for construction of additional lanes to improve traffic flow between US 75 and PGBT.

Along northbound US 75, the additional lanes will allow for the existing traffic pattern to be reconfigured so that vehicles trying to exit onto 15th Street will not have to cross the path of traffic entering US 75 from PGBT.

When the project is complete, northbound motorists on US 75, wishing to get to 15th Street, will have to use the Plano Parkway exit, farther south. Eliminating the current exit and creating an entry-only onto US 75 will ease traffic flow in that area, which now backs up with motorists trying to safely enter US 75 from PGBT, while at the same time, others try exiting US 75 to get to 15th Street.

On the southbound side, the existing ramp from 15th Street will be relocated farther north and a new braided ramp will be constructed allowing traffic to enter and exit US 75 without having to merge with each other. With the braided ramp, the southbound US 75 exit to Plano Parkway will weave under the southbound US 75 on-ramp.

The project spans 1.3 miles, with an ultimate goal of eliminating the congestion that motorists encounter when transitioning between US 75 and the Bush Turnpike. The work is expected to take more than two and a half years to complete.
