*Updated asphalt schedule provided below
Smoother roads are up ahead for frontage roads east of Welch Road.
Along eastbound and westbound LBJ between Welch and Preston Road, most frontage roads will soon be paved with stone-matrix asphalt, or SMA, which will be the final and permanent layer of asphalt for the scheduled areas.
SMA pavement operations are monumental along the LBJ Express project. Since construction broke ground, frontage roads were the first to be ripped up, torn out and reconstructed with temporary pavement while utility relocations, roadway drainage installation and other roadway construction prerequisites ever took place.
During the construction phase, frontage roads were paved about 1.25 inches below final grade, which is acceptable for driving but is not the last layer. This explains why some sections of roadway, such as those where drainage inlets were installed, appear slightly elevated compared to the rest of the pavement. These elevated sections around inlets are tapered to provide a smoother transition for drivers.
With SMA on the schedule, it typically is a sign that the digging and trenching is complete in the area, and what is left is surface work such as aesthetical improvements, including permanent paving. SMA will even out transitions and will provide a much better driving experience for commuters.
Drivers may have already gotten a taste of driving on SMA-paved roads on the completed sections of LBJ. Prior to our Phase One opening last December, large stretches of frontage roads and main lanes between Preston and Coit Road were paved in long runs, leading to full lane closures.
Being one of the final things to cross off the list before being considered “complete,” paving the last layer of surface dressing all at once in long stretches will provide a much better quality end product, with less joints and more durability. This means that the roadways are usually fully closed when paving SMA.
Schedule of Operations
Throughout the months of October going into November, the LBJ team plans to pave SMA on frontage roads between Welch and Preston. Motorists may experience some delays while work is being performed, and are advised to plan ahead and seek alternate routes, if possible. Schedules provided below are subject to weather and other unforeseen issues, and may be postponed or delayed.
WESTBOUND FRONTAGE ROAD BETWEEN MONTFORT AND THE DNT (Almost Complete)
Friday, Oct. 17 between 9pm and 10am (overnight)
Full closure of the westbound frontage road between Montfort and the DNT to facilitate in final asphalt operations. Noel Rd. at the westbound frontage road will also be closed at this time. Detour: Westbound traffic will take northbound Montfort onto Alpha Rd., until Inwood to maneuver around the closures.
EASTBOUND FRONTAGE ROAD BETWEEN MONTFORT AND PRESTON & AT MONTFORT INTERSECTION
Sunday, Oct. 19 between 4p.m. and 6 a.m. (overnight) & Monday, Oct. 20th between 8 p.m. and 6 a.m. (overnight)
- Eastbound frontage road between Noel Rd. and Montfort will be closed
- Eastbound frontage road at the Montfort intersection will be closed
- Eastbound frontage road between Montfort and Preston will be closed.
- Westbound frontage road at the Montfort intersection will be open at this time.
Detour: Eastbound frontage road traffic may take southbound Noel Rd. and use Harvest Hill and Preston to maneuver around the closures.
WESTBOUND FRONTAGE ROAD BETWEEN DNT AND WELCH
Tuesday, Oct. 21 between 9 pm and 10 am(overnight)
Full closure of the westbound frontage road from DNT to Welch. Driveways along this road will also be closed. Detour: Westbound traffic may use Dallas Parkway, Alpha Rd. and Welch Rd. to maneuver around the closures.
- EASTBOUND FRONTAGE ROAD BETWEEN WELCH AND THE DNT (Oct. 1-3)
- EASTBOUND FRONTAGE ROAD BETWEEN DNT AND MONTFORT (Oct. 9-13)
Sections Still Pending for SMA Placement:
- Westbound frontage road between DNT and Welch
- Eastbound frontage road at Montfort intersection
- Eastbound frontage road between Montfort and Preston
- Westbound frontage road at Montfort intersection
- Westbound frontage road at Welch intersection
- Eastbound frontage road at Preston intersection
- Westbound frontage road at Preston intersection
* Information on SMA paving and associated closures will be updated accordingly, as scheduled.
Note: Operations may be postponed or delayed if necessary due to weather, equipment issues, scheduing, etc.
