Myers and Sons Construction, LP (Myers) was awarded this project by Caltrans District 3. The project rehabilitated a section of U.S. Highway 50, known as the W/X Viaduct, between 18th and 24th Streets. Built in 1968, this section of freeway is comprised of two 2,530 foot-long parallel structures approximately 90’ foot-wide that carry six lanes of traffic over city streets, freight, and light rail lines in downtown Sacramento with approximately 250,000 vehicles travelling on the Viaducts daily. 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 project broadly included 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 146 steel column casings for seismic strengthening, widening shoulders, adding new joint seals, new concrete barriers and railings, energy-efficient lighting standards and enhancing safety. The work zone was highly travelled by pedestrians, bicyclists, cars, light trucks, semi-trailer trucks, buses, freight trains and passenger trains. The project presented the possibility that any impedance to the through traffic significantly increased the risk of impacting local businesses, commuter traffic, statewide and nationwide commerce, and emergency response vehicles. Myers completed this project ahead of schedule earning Myers a multimillion dollar bonus.
