Where is the work happening?

The closure will take place in Sacramento on the elevated section of U.S. Highway 50 known as the W/X Viaduct, south of downtown, between 18th and 24th Streets.


When does the project start?

Traffic-interfering work on the project will occur in two stages:

  • Eastbound US Highway 50 – Phase 1 & 2: April 22 – May 21 (COMPLETE)
  • Westbound US Highway 50 – Phase 1 & 2: May 27 – June 19

Non-traffic interfering work will take place through the spring, summer and fall of 2014.


Will the whole highway be closed?

Two- three through lanes on the construction side will be open. Traffic in the opposite direction of construction will be fully open as normal with no impact.


Will the highway be closed at night too?

Work will continue 24 hours a day during each phase.


Will there be any ramp closures?

During Eastbound, Phase 1, the following ramps will be closed:

  • 11th Street On-Ramp

During Eastbound, Phase 2, the following ramps will be closed:

  • 11th Street On-Ramp
  • 16th Street On-Ramp
  • Connector ramp from eastbound Highway 50  to southbound Highway 99
  • Connector ramp from eastbound Highway 50  to eastbound Business 80

During Westbound, Phase 1, the following ramps will be affected:

  • Only one lane will be open on the Connector ramp from northbound Highway 99 to westbound Highway 50, as well as the connector ramp from westbound Business 80 (Cap City Freeway) to westbound Highway 50.

During Westbound, Phase 2, the following ramps will be closed:

  • 16th Street Off-Ramp
  • Connector ramp from westbound Business 80 to westbound Highway 50
  • Only one lane will be open on the Connector ramp from northbound Highway 99 to westbound Highway 50


Will any phases finish early?

Eastbound Phase 1 work finished 5 days early:
Updated Schedule: April 22 – May 1
Original Schedule: April 22 – May 6

Eastbound Phase 1 work finished 5 days early:
Updated Schedule: May 2 – May 16
Original Schedule: May 7 – May 21

Westbound Phase 1 work will finish 4 days early:
Updated Schedule: May 27 – June 6
Original Schedule: May 27 – June 10

Westbound Phase 2 work will begin 4 days early:
Updated Schedule: June 11 – June 19
Original Schedule: June 6 – June 25

Since Westbound Phase 2 is beginning early, it is possible that it will also complete early. However, that possibility will not be known until we get closer to the end.


Why is this project happening?

Age and heavy use have caused extensive wear and cracking on the deck between 18th and 24th Streets. The roadbed, which was built in 1968, needs to be completely resurfaced in order to reduce recurring maintenance costs, and increase the life of the concrete deck. The existing highway deck will be sealed with a protective coat to minimize future cracking and a new four-inch thick slab of concrete will be applied and secured to the girders.


Is Caltrans taking into consideration other Spring/Summer projects and events?

Caltrans tried to schedule this important project during the summer months to avoid the 2014 USA Track & Field Championships, the Fourth of July, the California State fair, the beginning of school sessions, as well as to avoid high summer temperatures, which are not conducive to this type of pavement work.  However, not everything can be avoided. Our community partners asked us to avoid closures during the State Fair in July so the construction period chosen is based on that.

What impacts will come from the “80-Across the Top” project?

The I-80 High Occupancy Vehicle (HOV) Project, also known as the “80 – Across the Top” Project, is an ongoing, four construction season project.  This project is entering its third construction season and currently under winter suspension.  Construction work will commence as soon as conditions are favorable for suitable prosecution of the work.  Traffic staging is planned to facilitate the reconstruction of the outer lanes in the eastbound direction starting in May, 2014 through March, 2015.  There are currently three lanes available in the eastbound and westbound directions.


What impact will this project have on traffic?

There will be significant traffic delays on the Viaduct, as well as on other freeways and roadways serving the Sacramento area. Plan your commute route now using the alternate route maps to avoid confusion when the project starts. Commuters can help to reduce traffic congestion by temporarily changing work schedules to avoid rush hour, carpooling, reducing unnecessary trips, and using other forms of transportation such as biking, walking, or Sacramento Regional Transit (Light Rail and bus) system.


Is the W/X Viaduct structure safe?

The W/X Viaduct is safe to drive on. There are no structural problems — only the top surface deck needs work to be resurfaced. Although there are no safety problems with the Viaduct, the completed project will also enhance future safety and traffic operations by creating wider shoulders and installing new joint seals, new concrete barriers and railings, new energy efficient lighting standards, and steel column casings for seismic strengthening.


What is the easiest way to get updates about the project?

Sign up for news updates about the project here:


What does the non-traffic interfering work include?

Non-traffic interfering night and weekend work will continue throughout the year. This work includes permanent striping, continued seismic retrofitting of the columns underneath the viaduct, and lighting and fencing work in the parking lots beneath the project area. Final completion is expected in December 2014.


What will Highway 50 look like after the closure?

The existing highway deck will be sealed with a protective coat to minimize future cracking and a new four-inch thick slab of concrete will be applied and secured to the structure.

The completed project will include wider shoulders, new joint seals, new concrete barriers and railing, new energy-efficient lighting, and steel column casings for seismic strengthening.
