SR 80 (Southern Blvd) Bridge Replacement Project
November 1 to November 30, 2018
- Demolition of main bridge’s bascule piers
- Install temporary construction walls
- Install gravity wall on the south side of the Southern Boulevard Causeway
- Install sidewall on the south side of the Southern Boulevard Causeway
- Exploratory drilling for replacement bridge foundations
- Testing of drill shafts for replacement bridge foundations
The Southern Boulevard Temporary Bridge, Flagler Drive and Southern Boulevard will be closed for brief periods between 9 a.m. and 4 p.m. from Monday, Nov. 5, to Friday, Nov. 9, as load testing is performed on test drill shafts south of the temporary bridge. The navigable Intracoastal Waterway through the temporary bridge also will be briefly closed to boat traffic during these times.
The duration of the closures will be for approximately 10 to 20 minutes and will occur on Flagler Drive from Flagler Promenade North to Harbor Towers & Marina Condominiums and on Southern Boulevard from Washington Road to State Road A1A/South Ocean Boulevard.
For testing purposes, three drill shafts have been constructed in the Intracoastal Waterway to collect critical data for the replacement bridge’s foundations. The testing procedure includes applying a small controlled explosive charge to the top of the shaft. The brief road closures are an added precaution to keep the public out of the testing area.
The navigable Intracoastal Waterway (ICCW) through the Southern Boulevard Bridge will have half-channel closures from 6 a.m. to 6 p.m. Monday through Saturday. A full channel opening may be requested during those times if four-hour notice is provided by calling Project Superintendent Clay Bores at (407) 488-0738. During half-channel closures, the horizontal clearance through the bridge is 40 feet. The Southern Boulevard Bridge opens for marine traffic twice per hour at 15 minutes and 45 minutes past the hour.
