Full 91 Project Construction Begins in July


While early construction of the 91 Project began this spring, full construction is heating up in July. Upcoming construction work includes: 

  • Lane restriping and carpool lane continuous access: Lanes on the 91, from the 71 to Serfas Club Drive/Auto Center Drive, will be restriped to shift drivers toward the median to allow construction crews to work along the shoulder. Carpool lanes between the 71 to Main Street also will be restriped to allow continuous access, rather than only at selected entry/exit points.  
  • K-rail placement along roadway shoulders: Concrete barriers, also known as K-rail, will be installed along the roadway shoulders to protect workers and drivers during construction. 
  • Staging activities for construction of new westbound 91 Green River Road off-ramp: Construction activities to build the new westbound Green River Road off-ramp and widen the Prado Road Bridge are expected to begin this summer, with most of the work taking place during the day.  
  • Sign installation throughout the corridor: Project signage, including reduced 55 MPH signs, will be installed along the 91 and 15 corridors. 

Stay tuned for details about upcoming construction activity expected to take place on the 15/91 connectors this summer. Plans call for restriping the northbound 15 to westbound 91 connector ramp to include two lanes.


The current number of lanes are expected to be maintained in each direction on the 91 and I-15 during peak travel hours, except during emergencies or special circumstances. Please drive safely, allow extra travel time and be alert to changing conditions within the project area.


The anticipated construction schedule (shown below) is subject to change and is available on the "Design-Build Schedule" section of the project website.


Anticipated Construction Schedule


Schedule subject to change; new lanes are anticipated to open in 2017.
