State Highway 121/183 Advance Planning
Fort Worth, TX
LAN prepared design schematics and environmental assessments and conducted public involvement for SH 121/183 (Airport Freeway) in Tarrant County from IH-820 to SH 161 as part of North Tarrant Express Project.
The 12-mile highway included 14 two-level interchanges and two four-level interchanges. Level of service studies were performed for the widening of the heavily traveled urban freeway from six lanes, to six general purpose lanes with four managed toll lanes. Geometric design for the reconstruction of all interchanges was included, in addition to a preliminary construction sequencing plan.
LAN incorporated value engineering accepted recommendations into the preliminary schematic, saving significant construction costs. LAN also proposed unique managed lane elevated sections to reduce impacts to adjacent businesses. The proposed road section alternatives were evaluated for environmental impacts versus construction costs using GIS modeling technology.
