The Department will be placing a concrete pile in the Loxahatchee River adjacent to the northeast side of the US-1 Jupiter Bridge on Monday, December 14, 2020, to test the riverbed subsoils in advance of the bridge replacement project, weather permitting. The test will provide information to better protect the adjacent Jupiter Lighthouse Museum and Lighthouse during construction, better enable the bridge replacement schedule to be met, and reduce the overall construction cost of the project.
A work barge will arrive with the concrete pile on December 9, 2020. Completion of the foundation testing is anticipated by Friday, December 18, 2020. All work will occur during daylight hours.
The foundation testing will not affect vehicular traffic on the existing bridge or vessels from accessing the navigational channel.
Construction of the US-1 Jupiter Bridge Replacement project is scheduled to begin in the Summer of 2021 and last through the Summer of 2025. This includes a full bridge closure and detour beginning in the Spring of 2023. The bridge closure will be preceded by temporary intersection improvements to improve traffic flow during construction at: Indiantown Road/Alternative A1A; Indiantown Road/US 1; Alternate A1A/US 1, and a permanent intersection improvement at Alternate A1A/Old Dixie Hwy.
Once completed, the new US-1 Jupiter Bridge will include improved navigation clearances of 38 feet vertical and 125 feet horizontal; seven-foot buffered bicycle lanes; eight-foot sidewalks on both sides of the bridge, and a permanent Intelligent Transportation System (ITS) to improve traffic flow during and following construction. The construction cost estimate is $136 million.
