Plano, TX – At a regularly scheduled board meeting on Wednesday, Sept. 19, the North Texas Tollway Authority (NTTA) Board of Directors unanimously authorized project development services for State Highway (SH) 170 from SH 114 to IH 35W in Denton and Tarrant counties; SH 360 from Green Oaks Boulevard to United States (U.S.) 287 in Ellis, Johnson and Tarrant counties and the Dallas North Tollway (DNT) Phases 4 and 5 in Collin and Grayson counties.
The services for these projects were authorized to further the environmental clearance process for each corridor and fast track project development. Each contract will encompass preliminary concept development and analysis, schematic design, environmental documentation and public involvement support.
“Although the SH 170 and SH 360 projects are subject to the market valuation process outlined in SB 792, in the interest of keeping these critical regional projects moving forward, the NTTA board has authorized contracts in excess of $6,000,000 to bring each project closer to completion as we seek to solve our regional mobility challenges,” said NTTA Board Chairman Paul N. Wageman.
“This action demonstrates NTTA’s desire to fast track projects. We will continue to work with our regional partners to support the final delivery of these projects to the citizens of north Texas,” said Jorge C. Figueredo, NTTA Executive Director. “We recognize that a significant amount of work and study have already gone into each of these projects from our regional partners most notably the Texas Department of Transportation’s Fort Worth District.”
At their Sept. 19th meeting, NTTA board members emphasized NTTA’s strong commitment to working with its regional partners to deliver SH 170, SH 360 and DNT Phases 4 and 5. “We have been challenged to help ‘get them across the goal line’ and this reflects our commitment to do just that,” continued Wageman.
This initial section of SH 170 will be a new limited-access roadway in southern Denton and northern Tarrant counties. This 6.3-mile segment of the road will start at SH 114 and terminate at IH 35W; previously built frontage roads along the road will accommodate a toll road within the median. When completely built, SH 170 will extend from IH 35W to SH 199 in Parker County.
SH 360, a new limited access roadway in southeast Tarrant, northwest Ellis and northeast Johnson counties, is a 9.7-mile facility extending from Green Oaks Boulevard to U.S. 287. Northbound and southbound frontage roads along the alignment are open to traffic from Green Oaks Boulevard to the Southern Pacific Railroad (SPRR) crossing. A single frontage road on the west side of the alignment is operating with two-way traffic from the SPRR crossing to U.S. 287. The final phase of SH 360 will be from U.S. 287 to U.S. 67.
DNT Phases 4 and 5 will extend the DNT to meet the anticipated growth in northwest Collin, northeast Denton and southwest Grayson counties. DNT Phase 4, a six mile facility, will extend from U.S. 380 to Farm to Market (FM) 428. Collin County has already begun development of the future northbound service road that will open to traffic in 2008. DNT Phase 5 will further extend the DNT 11.6-miles from FM 428 to FM 121 into Grayson County.
