UFES Traffic Update – July 12, 2023

Map showing traffic limitations on Delaware Street.Traffic Pattern Changes starting July 17, 2023

Ongoing construction work for the UFES project will impact motorists at the intersection of S. Delaware Street and Pacific Blvd. Starting on July 17, 2023, and lasting for approximately three months depending on construction progress, the following traffic modifications will be:

  • Motorists traveling northbound on S. Delaware Street: NO left turns onto Pacific Blvd.
  • Motorists traveling eastbound on Pacific Blvd: NO left turns onto S. Delaware Street.

Some turning restrictions for properties in the vicinity of Pacific Blvd/S. Delaware St. will remain in place into October, and the left turn on to Pacific will be restricted intermittently for the next few months. There will be typical construction activity and noise during work hours.

Currently, all lanes of S. Delaware Street are open in both directions, with the exception of the intersection with Saratoga Drive where traffic is restricted to one lane in each direction. All lanes of Saratoga Drive are currently open with the exception of lane restrictions at the Event Center Main Entrance.

Traffic patterns will continue to be updated as needed. Please watch for signs indicating traffic pattern changes, and allow extra time in your travel plans to accommodate the new traffic patterns.

Please visit our UFES Project Page for complete project details.

*Construction schedules and traffic patterns are subject to change.
