The following is an update of NTTA actions in response to inclement weather:
The NTTA System is open and passable. Icy patches are possible and drivers must adjust their speed to match current conditions. Drivers are encouraged to use caution, slow down and allow extra distance between vehicles when driving on all roadways in the Metroplex.
- NTTA crews began 12-hour shifts Sunday, Feb. 22 at noon. This schedule will continue for the duration of this winter weather event.
- As we see a transition from rain to sleet/snow on the Chisholm Trail Parkway, Dallas North Tollway in Collin County and Sam Rayburn Tollway, NTTA roadway crews are applying salt and MD-20 (magnesium chloride) to prevent the formation of ice on the road, with special attention paid to bridges, interchanges and elevated surfaces on the NTTA system.
- NTTA has 104 people per shift either in trucks or operating equipment such as frontend loaders or skid steers for loading trucks with material. (CTP - 19, PGBT - 37, SRT - 34, DNT - 14). There are 95 plow or sanding trucks monitoring, treating and clearing roadways.
- Crews will continuously monitor any additional slick spots/ice and sand/apply deicer where necessary.
- NTTA asks drivers to keep a good distance from sand/de-icing trucks and plows to ensure the safety of both operators and motorists using NTTA roadways.
- Pavement sensors are positioned strategically at various locations around the NTTA System, and are located both on the roadway surface, sub-surface, and on elevated structures to obtain readings fully representative of temperatures affecting roadway surfaces.
Current roadway surface sensor readings are as follows:
- President George Bush Turnpike (PGBT) / Dallas North Tollway (DNT) Overpass: 32.2 degrees
- Sam Rayburn Tollway (SRT) / DNT: 32.2 degrees
- PGBT / IH-35 Overpass: 32.2 degrees
- PGBT / IH-635 Overpass: 32.7 degrees
- Lewisville Lake Toll Bridge: 32 degrees
- Chisholm Trail Parkway (CTP) / I-30: 33.6 degrees
NTTA is committed to providing the safest driving conditions possible for its customers. Drivers who require assistance on the NTTA System should call 9-1-1 to be connected to police dispatch, which will transfer the call directly to NTTA’s Command Center. The Command Center will then dispatch NTTA’s free Roadway Customer Service to the driver’s location. Drivers who are in need of assistance should, if possible, move their vehicle to the side of the road and stay inside the vehicle with a seatbelt securely fastened while waiting for assistance to arrive.
NTTA Snow/Ice Response Fast Facts:
- Follow NTTA on Facebook and Twitter (@TollTagTidbits) for the very latest information regarding current traffic conditions.
- There are two brine stations, as well as 13 material stockpiles, containing both magnesium chloride (Melt Down 20) and sand mixtures, placed strategically throughout the System for improved response times.
- As icy patches are identified, “Hot Shot” trucks from the Maintenance Department can be dispatched quickly to those specific locations to spot treat those areas with MD 20, the de-icing material, and sand.
- Many NTTA trucks are outfitted with global positioning satellite (GPS) equipment. During a snow or ice event, their locations are easily tracked, allowing the NTTA to quickly re-position vehicles for rapid response to trouble spots on the roadway.
- Maintenance crews can treat all elevated structures throughout the System every hour, and the entire System can be treated in less than two hours.
- The NTTA snow and ice plan has a designated route for each truck to ensure every mile of our roadways is sanded every hour. If a truck is a few minutes in front of a driver or a few minutes behind a driver or if they are re-filling their spreader it is very possible to drive an NTTA roadway without observing a sand truck.
About the NTTA
The North Texas Tollway Authority (NTTA), a political subdivision of the state of Texas, is authorized to acquire, construct, maintain, repair and operate turnpike projects in the north Texas region. The nine-member board is comprised of Chairman Kenneth Barr; Vice Chairman Bill Moore; and Directors William D. Elliott, Matrice Ellis-Kirk, Mojy Haddad, Gary Kloepper, Michael Nowels, George "Tex" Quesada and Jane Willard.
The NTTA serves Collin, Dallas, Denton, Tarrant and Johnson counties and is responsible for the NTTA System, consisting of the Sam Rayburn Tollway, President George Bush Turnpike, Dallas North Tollway, Addison Airport Toll Tunnel, Lewisville Lake Toll Bridge, Mountain Creek Lake Bridge and the Chisholm Trail Parkway. The NTTA is able to raise capital for construction projects through the issuance of turnpike revenue bonds. NTTA toll projects are not a part of the state highway system and receive no direct tax funding. Tolls are collected to repay debt and to operate and maintain the roadways.
