Description
The Dallas High Five Project is the intersection of Interstate Highway 635 with North Central Expressway US 75, a first-level stack interchange in Dallas, built to ease the flow of traffic to half a million vehicles per day.
As part of the project, Interstate Highway 635 was widened to include HOV lanes. The new lanes for regular traffic were built on the outer vacant right-of-way, while the HOV lanes were built in the median.
The 5 central ramps/bridges were designed to be built with the balanced cantilever segmental concrete construction method, while all other ramps and approacher were built with precast concrete U beams. Precast segments were used in the construction of bridges to minimize traffic impact.
