Permanent Repairs of Hwy 17A Overpass – Highlights and Resources for Businesses

UPDATE - January 22, 2024 | Work is progressing well for the repairs, so despite the weather, the following updates have been shared by MOTI:

  • Work on the Highway 17A Overpass Project was cancelled for Friday and Saturday night; January 19th & 20th, due to weather. The remaining snow on the overpass posed a hazard to crews and could not be removed as this would create a hazard for traffic travelling underneath the overpass.
  • The nightly closures of Highway 17A southbound from 7PM – 5AM resumed on Sunday night, January 21st.
  • There will be at least one more full Friday-Saturday closure of Highway 17A southbound for the bridge deck pour. Date to be determined.

The next upcoming full closure is still expected to be this weekend. Details are below and continue to be relevant.

The first lane on the far left is usually for Southbound traffic and it has been closed since the overpass was struck in July. The second lane on the left is usually the Northbound HOV lane and it has been temporarily re-allocated as a Southbound thru-lane until construction is complete but with nightly closures and some weekend closures. The third lane is the Northbound thru-lane. This lane remains open. The last lane is the on-ramp to Hwy 99 Northbound and this lane remains open.
