Greetings from the field! Since the last issue of From the Field, a great deal of progress has been made on the 91 Project. Overall construction is now approximately 80 percent complete, and we are looking forward to opening the new lanes during the first half of 2017. For a summary graphic of our construction statistics, please click here.
We're excited to have reached two major milestones recently with the opening of new ramps. These ramps were closed in 2015 as part of our "Main Street Squeeze" effort, and we appreciate the community's patience and support of local businesses during these closures:
1. The westbound Main Street off-ramp opened July 14. Please note that as a temporary condition, only right turns are allowed from the ramp onto Main Street to allow crews to continue to work in the area.
2. We also reopened the eastbound Main Street on-ramp to the 91 in June. Watch for news in the near future about the opening of the Main Street on-ramp to northbound and southbound Interstate 15.
We recently revamped the interface of our weekly Construction Alerts to make it easier to search by closure dates, direction of travel and location. Please take a look and let us know your thoughts.
Be on the lookout for the following work ahead:
1. A full closure of westbound 91 at the 71 is scheduled from Saturday, July 23 at 11 pm to Sunday, July 24 at 7 am to allow crews to safely install an overhead sign near Coal Canyon. Suggested detour routes include:
  • Northbound I-15 to westbound 60 to southbound 57; or
  • Northbound 71 to westbound 60 to southbound 57
The following ramps also will be closed:
  • Lincoln Avenue westbound on-ramp
  • Maple Street westbound on-ramp
  • Southbound 71 to westbound 91 connector
  • Green River Road westbound off-ramp
  • Green River Road westbound on-ramp
Please allow extra travel time, expect delays and avoid the area, if you can. Also please follow detour signs, carpool, if possible, and remember that the speed limit is 55 MPH within the construction limits. For real-time traffic information, go to
2. There will be weekend full closures of the westbound Lincoln Avenue on-ramp and the eastbound Lincoln Avenue off-ramp from Friday, July 22 at 9 pm to Monday, July 25 at 4 am. During the westbound on-ramp closure, Pomona Road will be closed to through-traffic between Lincoln Avenue and Smith Street. Local business access will be provided.
3. Full nighttime closures of the eastbound 91 near Interstate 15 will be continuing through August, Monday through Saturday nights. Please follow our Construction Alerts for more details by registering at or emailing
4. The Buena Vista undercrossing at the 91 will be closed from Saturday, July 23 from 9 am to 5 pm and from 9 pm to 5 am to allow crews to lower the bridge. If necessary, the undercrossing may be closed on Monday, July 25 from 9 pm to 5 am to continue work. No pedestrian access will be available during the closure. Motorists and pedestrians can use West Grand Boulevard or Lincoln Avenue as alternate routes.
5. Please remember that the westbound Serfas Club Drive off-ramp closed on July 5 for approximately two months. As a detour, motorists can take the westbound 91 Maple Street off-ramp, travel north on Maple to Pomona Road, and then head west on Pomona Road to access Auto Center Drive/Serfas Club Drive.
