Harris County Toll Lanes

This design-build-finance-operate-maintain project constructed four express toll lanes down the center of State Highway 288 for more than 10 miles. With toll rates based on the day of the week, time of day, number of axles, and historical utilization, these managed lanes alleviate traffic congestion between southern Harris County and downtown Houston.

As part of the project, the team reconstructed more than 50 bridges in just 1,000 days, including 18 structures that are direct connectors. The interchanges contain high-level directional flyover ramps measuring up to 1.3 miles long, long-span post-tensioned straddle bents and sharply curved girder bridges.
