Impacts to U.S. 89
Intermittent daytime closures during off-peak hours can be expected in either direction on U.S. 89 throughout the project duration while crews complete work items like barrier, wall panels and paint restriping.
With warmer weather, we also see an increase in people enjoying the outdoors. The project team would like your help in keeping the project safe by reminding you to stay out of the work zone. Please do not walk, roll, or ride on the bridges, in the work zone, or behind the barrels on the frontage roads, bridges and neighboring streets. U.S. 89 is closed to bicycles and pedestrians.
Crews are working to complete sidewalks and pedestrian access routes as concrete supplies allow. We appreciate your help in keeping everyone safe.
Upcoming Impacts by Area
Northbound Main Street On-Ramp Now Closed Through Early September
The northbound US-89 on-ramp from Main Street is now closed through early September for utility installation and ramp reconstruction. Motorists can access northbound US-89 via the 400 North interchange or Park Lane.
Crews continue building the new lanes on US-89 and setting forms on the bridge deck (driving surface) with concrete placement anticipated in late August or early September so that crews can complete the west frontage road tie-in to the bridge. The bridge will open to traffic this fall.
Excavation of the old southbound US-89 lanes and new storm drain system installation is now underway, continuing through July. Excavation and construction of the bridge substructure and retaining walls are also underway. Area residents can expect an increases in construction activity, noise and vibration during the day through the summer. This bridge is anticipated to open to traffic before the end of the year.
The east frontage road is reduced to one-way travel with a temporary signal through early August. Please pay attention to the signal and wait for your turn.
No Right-Turn Access from Antelope Drive to Hobbs Creek Drive through July 27
Access from Antelope Drive to south Hobbs Creek Drive is closed while crews rebuild the southwest quadrant of the interchange. There will be no right-turn from eastbound Antelope Drive to southbound Hobbs Creek Drive. Traffic will be detoured from Antelope Drive to SR-193 and can access southbound US-89 from there until the southbound on-ramp can be opened around July 27.
Local residents can use Oak Lane as an alternate route from Antelope Drive or Gordon Avenue to Hobbs Creek Drive.
Antelope Drive Southbound On-Ramp to open when Hobbs Creek Drive Access Closes
As early as July 27, the on-ramp from Antelope Drive to southbound US-89 will open to traffic and access to the south side of Hobbs Creek Drive from Antelope Drive will close. This will allow crews time to construct the southwest portion of the interchange through fall. No other ramps will open at this time.
Local traffic can access Hobbs Creek Drive from the Gordon Avenue interchange or from Antelope Drive via Oak Lane.
Hobbs Creek Drive; Oak Lane – 1800 North Utility Work
Beginning as early as July 27, storm drain installation will close sections of Hobbs Creek Drive south of Antelope Drive. Local access will be provided to area residents in the closure area. Other local traffic can use Oak Lane as a detour.
Valley View Drive Near SR-193
One-way traffic operations are in place through August while crews complete reconstruction and paving work.
The northbound off-ramp to SR-193 has been shifted south to allow space for reconstruction and widening. Drivers can anticipate an earlier exit point, narrowed lane, and crews nearby.
