FDOT will be performing a foundation test in advance of the upcoming US-1 Jupiter Bridge Replacement project. The test will consist of placing one concrete pile in Loxahatchee River adjacent to the northeast side of the US-1 Jupiter Bridge. The anticipated duration of the foundation testing is from December 15th through December 19th. The testing will not affect vehicular traffic on the existing bridge or vessels from accessing the navigational channel. Please click here to view the press release that includes more information.

The Florida Department of Transportation will replace the SR 5/US 1 Bridge over the Loxahatchee River/Intracoastal Waterway in the Town of Jupiter. The replacement bridge will consist of two 11-foot travel lanes in each direction, 8-foot sidewalks and 7-foot bike lanes in both directions. Pedestrians will be separated from traffic with permanent concrete barriers. The new bridge will be a twin double-leaf drawbridge with up to 42 feet of vertical clearance and a navigable channel width of 125 feet. The new bridge also will feature a concrete bridge deck to reduce traffic noise, a new tender house and pedestrian overlooks. In preparation for a 20-month bridge closure and detour, temporary intersection improvements that consist of additional turn lanes will occur at: US 1 at SR 706/Indiantown Road, Alternate A1A and SR 706/Indiantown Road and US 1 and Alternate A1A/Beach Road. Permanent intersection improvements also will occur at Alternate A1A and Old Dixie Highway. Intelligent Transportation System devices will be installed to improve traffic flow.
