The North Texas Tollway Authority has opened the first four ramps on the Sam Rayburn Tollway/Dallas North Tollway interchange in Collin County on Monday morning, giving motorists on the SRT direct access to the DNT.
The new ramps will provide all of the interchange’s connections from the SRT to the DNT. Motorists on southwest-bound SRT will directly connect to north- and southbound DNT and, motorists on the northeast-bound SRT main lanes will directly access both the north- and southbound DNT main lanes.
“We are pleased that these four major ramps have opened to traffic ahead of schedule,” said Elizabeth Mow, NTTA director of project delivery. “The contractor and our staff have worked diligently, and we thank them.”
Mow said the ramp openings are expected to improve traffic flow through a busy area of Frisco and Plano. As an added convenience, one of the new ramps leading to the DNT includes a connection from the southwest-bound SRT frontage road (SH 121) just west of Preston Road. This means frontage road drivers near Preston Road and the Stonebriar Centre mall in Frisco will be able to directly access the north- or southbound DNT main lanes via the ramp connector, bypassing traffic lights at the intersection of SRT and DNT.
The new cashless toll gantry at this connector will cost .23 cents for a passenger vehicle with a TollTag or .45 cents for a passenger vehicle using ZipCash, the NTTA’s pay-by-invoice system. Toll rates vary by the number of axles on a vehicle; for more information on toll rates, please go online to www.ntta.org/AboutUs/TollRates/.
Construction is ongoing to finish the remaining four ramps on the SRT/DNT interchange; the last four ramps, which will connect the DNT to the SRT, are expected to open to traffic in January 2012.
Crews began construction of the SRT/DNT interchange in February 2010. The five-level interchange was designed to be compact and to feature eight ramps joining the two major toll roads.
Between now and when the interchange fully opens, crews will continue to close DNT and SRT main lanes and frontage roads to complete critical tasks. Lane and ramp closures will continue each weeknight, during off-peak daytime hours and during the weekends.
