NTTA Awards Its Largest Contract Ever The NTTA Board of Directors has awarded its largest single contract to date to fund construction of segment four of the 121 Tollway, which includes the 121 Tollway/U.S. 75 Interchange in Collin County.
The contract was awarded to W.W. Webber, the firm that came in with the lowest offered bid – nearly $220 million.
The contractor will construct a 2.94-mile stretch of the 121 Tollway in Collin County from Hardin Boulevard to the east of Medical Center Drive, including the 121 Tollway/U.S. 75 Interchange within the City of Allen, the City of McKinney and the Town of Fairview. The four-level interchange will feature six direct-connecting ramps to provide main lane access between the two roadways. The NTTA also will construct a loop ramp configuration connecting to the service roads.
The interchange is expected to open in January 2011.
“The NTTA will formally execute the contract with W.W. Webber and start construction after environmental approval for the project is received from Texas Department of Transportation and the Federal Highway Administration,” said NTTA Director of Project Delivery Elizabeth Mow. “This milestone contract means continued progress on the 121 Tollway project and our dedication to improving mobility in the area.”
The contract award is the latest development on the 121 Tollway project, which consists of the following segments:
Segment 1 – 7.05 miles, from Denton Tap Road in Coppell to Old Denton Road in Carrollton; open to traffic.
Segment 2 – 9.02 miles, from Old Denton Road in Carrollton to Hillcrest Road on the Plano/Frisco line; opened to traffic on Aug. 31.
Segment 3 – 6.88 miles, from Hillcrest Road to Hardin Boulevard; currently under construction and scheduled to open by January 2010.
Segment 4 – 2.94 miles, from Hardin Boulevard to the east of Medical Center Drive including the 121 Tollway/U.S. 75 interchange; is scheduled to open by January 2011.
Segment 5 – .33 miles, consists of adding direct-connect bridges to the 121 Tollway at the Dallas North Tollway; is scheduled to open by January 2012.
The 121 Tollway officially transferred to the NTTA System on Sept. 1, 2008 from the state highway system overseen by the Texas Department of Transportation (TxDOT).
