About The Project

Caltrans rehabilitated a section of U.S. Highway 50, known as the W/X Viaduct, between 18th and 24th Streets 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 had extensive cracking on the deck and were in need of rehabilitation in order to enhance safety, reduce recurring maintenance costs, and increase the life of the concrete decks.

The newly rehabilitated roadway includes:

  • A new 4-inch concrete deck was placed on top of the existing deck and tied to the girders
  • Repaired cracks in the original deck
  • Added steel column casings for seismic strengthening. (These will officially complete by December 2014)

The service life of the structure decks are extended to about 20 years, which will significantly reduce maintenance expenditures.

The completed project also provides widening at the shoulders, new joint seals, new concrete barriers and railings, energy-efficient lighting standards, and enhanced safety.
