Jones|Carter partnered with Montgomery County to reconstruct two miles along Lone Star Parkway from TX-105 to FM 149. The project was necessary to help mitigate traffic congestion and improve mobility in the region. In 2015, Montgomery County passed a Road Bond Package featuring Lone Star Parkway as a significant project. Innovative construction methods were necessary to keep the project within budget and on schedule.
Prior to reconstruction, Lone Star Parkway was a two-lane, 22-foot asphalt roadway with no paved shoulders. With an average daily traffic of 7,000 vehicles, a 45 mph speed limit, and limited travel space along the roadway, driver comfort was a concern that J|C accounted for in their design.
J|C performed a topographic survey with 100-foot cross sections for the entire two-mile corridor. The data for the cross sections was used to help develop the roadway design and roadside elements, such as roadside ditches.
The J|C team prepared final construction plans to rehabilitate and widen the roadway. The proposed roadway width of 26 feet includes two widened 12-foot lanes and two 1-foot shoulders. The widening of the road helped to improve driver comfort and mobility in the area. The J|C team analyzed several options to provide cost savings, one innovative construction method used was to pulverize the existing pavement and base, which had to be removed prior to reconstruction, and use it in the base layer of the new pavement structure.
Due to all of the considerations taken during the design phase of Lone Star Parkway, safety along the corridor has improved since construction was completed in November 2017.
