This $2.5 billion design-build project rebuilt several of Tarrant County’s most congested highways; IH-820, SH 121, and SH 183. The project improved mobility by increasing the existing road capacity with a combination of general-purpose lanes, continuous frontage roads, and managed toll lanes.
Aguirre & Fields designed 12 bridges, ancillary illumination/tolling/signage (ITS) structures, and 65 retaining walls. NTE West Segment is 6.4-miles in length and runs from the IH-35W interchange to the SH 183 split along IH-820. It crosses the cities of Fort Worth, Haltom City, and North Richland Hills.
Aguirre & Fields was the Bridge Lead for the dual-office production and package deliveries of 11 bridges including a 4,000-foot direct connector from SH 183 westbound to IH-820 southbound, 7 concrete girder bridges at Big Fossil Creek including two braided ramp systems, and 3 slab-beam bridges at Singing Hills Creek. The braided ramps and direct connectors included post-tensioned straddle bents. We also prepared the preliminary schematic arrangement for two direct connector bridges at the SH 183 split taking into account geometric and utility clearance requirements.
Aguirre & Fields also served as the project’s Retaining Wall Lead responsible for the geometric layout and design of 65 retaining walls consisting of MSE, cast-in-place spread footing, drilled shaft, noise, and freestanding walls.
Additionally, our team supervised design of 93 drilled shaft foundations for various ITS equipment poles and large sign supports for closed circuit television, microwave vehicle detector, dynamic message signs, and automatic vehicle detection.
