Lane was the prime contractor for the 10-mile reconstruction of Interstate 35 in the Waco region. The project includes 433,000 CY of PCC, 300,000 TN of Asphalt paving, 2 million CY of excavation and 26 bridges, including a signature bridge over the Brazos River and a direct connector bridge connecting FM 2013 directly to the northbound lane I-35. Project elements included new two-lane asphalt and concrete frontage roads, concrete reconstruction of six main lanes (three in each direction). The work involved high volumes of excavation and embankment, miles of box culverts and reinforced concrete pipe, soil nail wall installation, and temporary and permanent retaining walls.
Direct Connector Bridge
The Direct Connect Bridge is one of many critical milestones on the I-35 Highway Reconstruction project in McLennan County, TX. The bridge was completed in mid-April 2013, ahead of the 200 day contract schedule. The bridge enables the thriving community of Hewitt, TX to access northbound I-35 without impeding traffic at the current overpass. It has 18 spans, the heaviest girder weighs 250 tons, and more than 3,600 cubic yards of concrete was poured for the entire bridge deck.
TxDOT requested Lane to accelerate the construction of the Brazos River Bridges by six months because nearby Baylor University opened their new football stadium for their first game the last weekend in August 2014. The bridge serves as a main artery for both pedestrian and vehicular traffic to/from the stadium.
Major Bridge Structure
The Brazos River bridges are 620’ long extradosed bridges with continuous steel trapezoidal box girders. The extradosed bridge system is a hybrid design between a girder bridge and a cable-stayed bridge. These bridges, which include a 250’ main span and twin towers that rise 46’ above the concrete deck, are reported to be only the third location in the United States to utilize an extradosed bridge design.
Awards and Recognition
Lane was awarded 1st Place in ARTBA’s 2012 (Training Programs/State Level) for their Effective Use of Law Enforcement in Work Zones Training. The Brazos River Bridge portion of the project won the 2014 Engineering Excellence Award from the Florida Institute Consulting Engineers.
