US 89 Lane Restrictions

Drivers should expect northbound lane closures this weekend beginning at 5:30 a.m. Saturday, Sept. 18 until 7 p.m. Sunday, Sept. 19 when northbound U.S. 89 is reduced to one lane between 400 North and Oak Hills Drive and from Gordon Avenue to S.R.193 while crews shift the travel lanes.

  • Northbound U.S. 89 will be shifted west between Pinewood Lane and Mutton Hollow Road to allow for reconstruction on the east side. Drivers should be prepared for a new traffic configuration and follow the posted speed limit.
  • Also this weekend, northbound U.S. 89 will be shifted to the east at Antelope Drive and access from eastbound Antelope Drive to northbound U.S. 89 will be detoured via Hobbs Creek Drive to S.R. 193. See below for more information.

 Daytime lane restrictions have resumed on northbound U.S. 89 between Oak Hills Drive and Gordon Avenue while crews complete wall facing activities through September from 5 a.m. to approximately 2 p.m. weekdays.

 Nighttime lane restrictions are also scheduled through September while crews remove the forms from the new interchange bridges.

Antelope Drive Area Impacts

This weekend (Sept. 18-19), crews will shift northbound U.S. 89 onto the new northbound ramps. The left turn from northbound U.S. 89 to westbound Antelope Drive will be maintained as will the signal controlling southbound U.S. 89 traffic. Drivers turning left from northbound U.S. 89 at this location should use the left lane and be prepared for a traffic split. There will not be turn access from the ramps.

There will be no access from Antelope Drive to northbound U.S. 89 at the intersection. Access to northbound U.S. 89 will be detoured via Hobbs Creek Drive to S.R.193. through fall 2021. Motorists are advised to use Fairfield Road or Church Street as alternate accesses to S.R. 193 during this work.

Access to southbound U.S. 89 will remain in place at the intersection until later this fall when the interchange will be closed and southbound access temporarily relocated to the Gordon Avenue interchange via the new frontage road.

Impacts by Area


Nicholls Road Area: Utility work is ongoing along 1350 East and on the west side of Nicholls Road. One-way traffic operations are in place while crews complete installation of the new sewer and storm drain systems. This work is expected to be complete in October and the roadway will be repaved this fall.

Crews are rebuilding the center of U.S. 89 through fall between Main Street and 400 North. This work includes material excavation, utility installation, material placement, grading and compaction. Bridge work will also include ground improvements and use of large equipment through 2022. Area residents can expect ongoing noise, vibration and dust during the day while this work occurs.

650 North/Oakmont Lane Area: Utility work is ongoing on the east frontage road between 400 North and Oakmont Lane. Road re-construction and paving are scheduled in this area as early as September 24



  • Crews are working on the retaining walls and Crestwood Road bridge substructure through fall.
  • The west side frontage road between Crestwood Road and Mutton Hollow Road is scheduled to open later this fall. Area residents can expect ongoing materials hauling, placement and vibration through September.



Tanglewood Lane Closure

Tanglewood Lane is closed at the east frontage road while crews complete storm drain installation through mid-next week. Local traffic is detoured to Corral Drive. The east frontage road is not impacted.

 When this utility work is complete, crews will begin regrading the frontage road and intersection tie-ins. Area residents can expect ongoing truck traffic, materials placement, dust and vibration from roadway compaction in advance of paving, which is currently scheduled for early October.

 East Frontage Road; 1070 North to 900 North

One-way traffic operations are in place through early October on the east frontage road near 1070 North (Orson F) while crews complete the last remaining section of water line.

 Area residents can expect an increase in trucks, materials placement, vibration and compaction through early October.

Oak Hills Drive Area

The new interchange is open and widening is expected to begin on the northwest side of Oak Hills Drive. Expect intermittent one-lane flagging to resume during the day through September.

Woodridge Drive Cul-de-sac

Crews plan to construct the cul-de-sac at the end of Woodridge Drive as early as September 20. Area residents can expect an increase in trucks, materials placement, vibration and compaction for approximately one week.

 Valley View Drive North of Cherry Lane

One-way traffic operations will be in place beginning as early as Monday, Sept. 20 for approximately one month while crews install storm drain and irrigation lines on the west side. Please be prepared for additional travel time and observe the traffic signal or flagger instructions.

It might seem strange that we keep sharing this safety message with you, but we keep seeing people “exploring” our work zone. Please, for everyone’s safety, do not walk, run, jog or ride bicycles in the work zone. Please stay away from equipment, machinery, trenches and other site hazards. If you have questions about the project, please contact us via email or Facebook and we can provide more information, photos, or even video.
