Tollway lanes closing (June 24-27)

The main lanes of the Dallas North Tollway (DNT) will be closed in both directions between Gaylord Parkway and Headquarters Drive this weekend.  The Tollway section will close at 9 p.m. Friday night, June 24, and remain closed through 5 a.m., Monday morning, June 27.

The North Texas Tollway Authority (NTTA) has provided a map of this closure and the detour routes at the following link:

During this closure, all traffic on northbound and southbound DNT will be diverted onto the Dallas Parkway frontage roads and must pass through several traffic signals before re-entering the Tollway.

Drivers will experience delays in both directions on Dallas Parkway between Warren Parkway in Frisco and Legacy Drive in Plano throughout the weekend.  Use an alternate route such as Legacy Drive, Parkwood Boulevard, or Preston Road.

These road closures are part of NTTAs interchange construction project.

Road work on SRT exit ramps

From Matt Shaheen
County Commissioner

On the night of Saturday, May 21, crews constructing the Sam Rayburn Tollway (SRT) / Dallas North Tollway (DNT) interchange will reconfigure the traffic patterns at two SRT exit ramps in order to complete critical work on the project.

– The southwest bound SRT exit ramp to Legacy Drive will reopen after a long term closure that allowed crews to build new bridge support structures.

– The southwest bound SRT exit ramp to Parkwood Boulevard will close for approximately three months so that the contractor may build similar bridge support structures in that location.

Joe Jaynes/The County Line: Sam Rayburn Tollway update

By Joe Jaynes
The County Line
According to the North Texas Tollway Authority (NTTA), all major traffic movements on the Sam Rayburn Tollway (SRT) and US 75 Interchange are expected to be fully operational by the end of January.
This will almost complete the SRT project. The major piece left will be the interchange at the Dallas North Tollway (DNT), which is scheduled to be opened in early 2012.
After touring the project, the NTTA sent over the following facts concerning the SRT (it’s still difficult not to call this 121) that I thought you might find interesting:
* Overall the SRT is approximately 26 miles in length, stretching from Denton Tap Road in Denton County to east of US 75 in Collin County, linking the region’s fastest-growing communities with DFW International Airport;
* The SRT consists of 40 miles of concrete traffic barriers and more than 277 acres of concrete pavement;
* The volume of concrete used in constructing the SRT is enough to build a five-foot-wide sidewalk from Dallas to Minneapolis;
* The square foot area of concrete walls along the tollway is approximately the same square foot area as the face of the Hoover Dam;
* The SRT/US 75 Interchange is designed to handle 238,000 vehicles per day;
* 16 million pounds of steel beams are being used to construct the SRT/DNT Interchange. This is enough steel to reconstruct the Eiffel Tower or build 1 ? Gateway Arches in St. Louis;
* The SRT project used approximately 4 million cubic yards of fill, which was equates to 400,000 dump truck loads of dirt;
* If the dump trucks that hauled the dirt were lined up from end to end, they would stretch close to 1,890 miles — greater than the distance from Dallas to Boston;
* The SRT has more than a half acre of aluminum signs; and
* The sod used to cover this project would cover 325 football fields or three 18-hole golf courses.
Most important about this project is that Collin County received approximately $1.4 billion in funding from the NTTA for future transportation projects. This funding is called Regional Toll Revenue (RTR) funds.
RTR funds will be used on the US 75 expansion, which will be well under way by this time next year.
The total scope of the U.S. 75 expansion is from Spring Creek Parkway in Plano north through Allen, McKinney and Melissa to the Outer Loop just south of Anna.
In addition RTR funds are also being used for the expansions of virtually every major thoroughfare throughout Collin County including:
– SH 121 through Melissa
– FM 455 in Anna
– U.S. 380 through Farmersville
– U.S. 78 through the Wylie and Lavon areas
– U.S. 380 through Frisco
– U.S. 289 through Prosper and Celina
– Custer Road in McKinney
With the state facing a $25 billion shortfall it is safe to say that there will not be any new funding for transportation coming out of the legislature next year.
It is the RTR funding from the Sam Rayburn Tollway that is keeping Collin County’s major transportation projects moving and our economic development growing.
I look forward to keeping you updated on these important projects.

Happy Thanksgiving to you and your families.
