Construction Update

May 31, 2024

Ongoing Activities

Pedestrian Ramp Upgrades

• Construction crews are upgrading pedestrian ramps on eastbound 400/500 South at selected locations to comply with current ADA standards.
• Concrete requires several days to cure; please avoid using new ramps for up to seven days.
• Follow posted pedestrian detours for your safety.
• Traffic signal work and pedestrian push button upgrades are occurring concurrently with the ramp work.

Utility Adjustments

• Utility access adjustments are underway, including lowering manholes and valves.
• Jackhammers are breaking the concrete surrounding utility accesses.
• Temporary asphalt will fill gaps to allow machinery to remove old asphalt without damaging utilities.
• Expect increased percussive noise from jackhammering in nearby areas.

Traffic Impacts

• Sunday, June 2, 7 a.m. - 12 p.m., eastbound 400/500 South between 800 East and 1300 East will be reduced to one travel lane. Between 12 p.m. - 5 p.m., westbound 400/500 South will be reduced to one travel lane from 1300 East to 800 East. These lane closures are necessary to adjust utilities in the travel lanes.

Schedule & Impacts

• Pedestrian Ramps: Daytime work Sunday through Friday 7am to 7pm.
• Roadway: Nighttime work Sunday through Thursday 8pm to 7am.
• Temporary sidewalks closures during ped ramp demolition and reconstruction.
• Lane shifts and temporary lane closures during construction. 
• Nearby residents will notice construction-related noise and vibration.

Project Highlights:

This project involves removing old asphalt and placing new asphalt pavement to enhance this crucial east-west route. it also involves:

• ADA Ramp Upgrades: Modifications ensure sidewalk transitions are accessible to everyone.
• Adjusting Manholes: Lowering utility accesses (i.e., manholes and water valves) to allow for milling.
• Milling: Removing old asphalt which will make the roadway rough temporarily.
• Paving: Applying new asphalt for a smooth finish.
• Raising Manholes and Valves: Adjusting utility access points to the new roadway surface.
• Roadway Striping: Applying final paint for striping/crosswalks/messages to new pavement.

Safety

Sidewalk Closures

Construction of updated pedestrian ramps will require temporary sidewalk closures. Crews are working along the south side of 400/500 South throughout the corridor. Pedestrians are encouraged to use the north side of 400/500 South and follow posted detours.

Other Area Projects

Support Local Business

Shopping locally boosts the economy, generates tax revenue, and supports small businesses during construction, ensuring continued access to your favorite spots.
