The U.S. 290/Hempstead Corridor serves as the major transportation route from northwest Houston, traveled by as many as 270,000 vehicles daily where U.S. 290 intersects with I-610. Area’s population is expected to grow over 70% by 2040. Texas DOT awarded OHLA USA company OHLA USA Inc (OHLA USA), one of 13 contracts for the $1.27 billion reconstruction of 38 miles of heavily traveled freeway, which helped reduce congestion and improve safety throughout the corridor.
Specifically, OHLA USA added two lanes in each direction of a 2-mile segment of U.S. 290, stretching from Pinemont Drive to West 34th Street. The freeway now features five general purpose lanes in each direction, separated by a HOV lane, as well as reconstructed, two-lane frontage roads. The scope of work also included demolition of Pinemont Bridge and construction of a longer bridge that spans the lanes added to U.S. 290; widening of the Antione Bridge carrying U.S. 290 over Antoine Drive; aswell as repaving and drainage work.
Project’s totals included 385,000 cubic yards of embankment and 461,000 square feet reinforced concrete bridge deck. Texas DOT implemented multiple major milestones (incentive/disincentive) for expedited delivery amidst high traffic volume and constricted rightof-way. The crews worked alongside live traffic—it was moved onto the westbound lanes, so crews could build most of the eastbound side, then swapped back so workers could widen the westbound side. The project also required high-level collaboration between client, design consultants and contractor for expedient resolution of design and utility issues. It lays the groundwork for future Houston projects, including the eventual
- Freeway widening
- Bridge construction over live traffic
- Complex Maintenance of Traffic
