Caltrans is scheduled to rehabilitate a section of U.S. Highway 50, known as the W/X Viaduct, in 2014. Built in 1968, this section of freeway is comprised of two 2,530 foot-long parallel structures that carry six lanes of traffic over city streets, freight, and light rail lines in downtown Sacramento. These structures have extensive cracking on the deck and are in need of rehabilitation in order to enhance safety, reduce recurring maintenance costs, and increase the life of the concrete decks.
The project broadly includes:
- Placing a 4-inch concrete deck on top of the existing deck and tying it to the girders
- Repairing cracks in the existing deck
- Adding steel column casings for seismic strengthening.
- Improved traffic operations throughout the project area.
The service life of the structure decks will be extended to about 20 years, which will significantly reduce maintenance expenditures. The completed project will also provide widening at the shoulders, new joint seals, new concrete barriers and railings, energy-efficient lighting standards and enhanced safety.
Project Schedule: The project is broadly organized into two Stages:
- Stage 1 – May 2 - 22, 2014: Eastbound Highway 50
- Stage 2 – May 28 – June 17, 2014: Westbound Highway 50
