Greetings from the field! Since the last issue of From the Field, a great deal of work has been accomplished on the 91 Project. The next few months will continue to be busy with preparations to open the new 91 Express Lanes and new eastbound and westbound 91 lanes in spring 2017.

Please be on the lookout for the following full closures that are needed to remove the temporary support structures from the Lincoln Avenue Bridge. Please note that these dates are estimated and subject to weather and other field conditions. 
  • Eastbound 91 at Maple Street will be closed December 19-21 from 11 pm to 4 am each night. Motorists will exit at Maple Street, head east on Sixth Street to Lincoln Avenue, and then turn left to enter eastbound 91 at Lincoln Avenue and Second Street. 
  • Westbound 91 at Lincoln Avenue will be closed December 21-23 from 11 pm to 4 am. Motorists will exit the westbound Lincoln Avenue off-ramp, and then will re-enter westbound 91 at the new westbound Lincoln Avenue on-ramp, which is scheduled to open on December 21.
We are excited to be reaching some major milestones this month:
  • The eastbound 91 Main Street connector to northbound and southbound Interstate 15 opened December 11.
  • The westbound 91 Lincoln Avenue on-ramp will open to motorists on or about December 21.
Dates are subject to change, based on field conditions and weather. As always, please follow our Construction Alerts for more details by registering online or by email . Remember to check  before your commute and allow extra travel time. Updates are posted to the 91 Project Facebook , Twitter , and Instagram . Please email any suggestions related to traffic flow, signs, signals or general construction activities .

Other upcoming construction activities include:
  • Opening the westbound 91 Maple off-ramp, scheduled for January
  • Opening the Maple Street Bridge to two-way travel in January 

  • Completing the paving of the Sixth Street/Paseo Grande intersection, which is being delayed to January, due to rain
  • Establishing full roadway capacity of Sixth Street
  • Realigning Frontage Road
  • Improving the west end of Wardlow Road
  • Completing improvements to the southern end of Serfas Club Drive from the ramp to Pine Crest Drive; this work will require a weekend full closure in January. Please watch for details.
  • Ongoing nighttime closures of eastbound 91 at Interstate 15 through January for continued work on the Express Connector from eastbound 91 to southbound 15 and from northbound 15 to westbound 91. 
Finally, the California Highway Patrol is increasing enforcement along the 91, Interstate 15, Interstate 215 and other major roadways. Please be careful, follow speed limits, and do not drink and drive. The safety of our construction crews and your fellow motorists are at risk. Please help everyone arrive home safely this holiday season. 

Happy Holidays to you and your loved ones!
