SH 146 Baytown Grade Separation
Ferry RD, BS 146E
The project area has increasing traffic volumes and SH 146 is currently a discontinuous freeway. Traffic is currently routed to frontage roads that do not meet the design criteria for a high-speed freeway. In addition, traffic flow along SH 146 is currently interrupted by the existing signalized intersection at North Alexander Drive. Traffic is currently routed to frontage roads that do not meet design criteria for a freeway. SH 146 is also designated hurricane evacuation route. The predicted ADT increase is anticipated to exacerbate related timing and flow issues. The facility had 77 crashes during the period from 2015 to 2017. The truck volume on the facility is roughly 2,302 trucks per day and this represents 8.1% percent of the facility's AADT.
Construct 4 mainlanes and grade separation
The purpose of the proposed project is to address the capacity and design deficiencies listed above by developing SH 146 into a continuous major thoroughfare up to current freeway design criteria standards between BS 146 and Ferry Road. This will accommodate the ADT increase expected and improve LOS. The construction of a grade separation over North Alexander Drive will reduce expected operational issues at this intersection by allowing continuous flow of east-west traffic. The addition of lanes will also increase potential emergency carrying capacity of the roadway in the event of hurricane evacuation.
Less than $100 million
