Following a thorough vetting and scoring system for bidders, the Texas Department of Transportation (TxDOT) has awarded the contract to build the SH-99 segments in Liberty County.
Grand Parkway Infrastructure was selected to serve as the design-builder to develop, design, construct and maintain approximately 44 miles of SH-99/Grand Parkway Segments H, I-1 and I-2 in Chambers, Harris, Liberty and Montgomery counties.
According to a spokesperson at TxDOT, the toll-lane project begins at U.S. 59 and connects to the existing 1-2A portion, continuing on to SH-146 to ultimately complete the northeast segments of the 180-mile Grand Parkway loop.
SH-99, or the Grand Parkway, is the third beltway loop and considered the outer loop of the Houston-The Woodlands-Sugar Land metropolis and will be the longest beltway in the U.S. The loop was divided into 11 segments for funding purposes and the Liberty County segments are not the last segments to complete.
Grand Parkway Infrastructure, the selected design-builder, will build Segments H and I-1, a new tolled two-lane controlled access facility with intermittent four-lane sections for passing from U.S. 59 North to I-10 East (approximately 38 miles); Segment I-2 which includes four additional toll lanes from FM 1405 to SH 146 for approximately six miles; and upgrade the tolling equipment of the existing tolled four-lane facility from IH 10 East to FM 1405.
The Grand Parkway Infrastructure scope price for design-build in was approximately $855 million. Construction is expected to begin in early 2018 and is scheduled to be substantially complete in early 2022.
