Main channel of the North Fork of the St. Lucie River to be temporarily narrowed due to Crosstown Bridge construction


PORT ST. LUCIE – Boaters in the North Fork of the St. Lucie River should use extra caution while navigating the river’s main channel as it will be narrowed for five months due to construction relating to the Crosstown Parkway Extension Project.

Beginning on December 4, 2017 through April 30, 2018, the width of the channel of the North Fork of the St. Lucie River will be reduced to 33’ due to the construction of the temporary trestle (work platform). The trestle is required by permit for the construction of the bridge, and it also helps avoid and minimize environmental impacts to the river and the Savannas Preserve.

Boaters are asked to use caution in the area as there will be obstructions in the waterway. The contractor will implement a temporary boat traffic control plan to ensure safe navigation by including a clear path for boaters using buoys, lighting, and proper signage.

During this timeframe, the contractor also will implement periodic height restrictions, allowing clearance for boats that are 6’or lower only. These restrictions will take place as needed for the contractor to span the bridge and will be coordinated in advance with the U.S. Coast Guard. The anticipated dates for the height restrictions are as follows: December 6-11; December 19-20; January 9-12; February 5-6; March 5-9 and March 26-28. Please note these dates are tentative and could be adjusted slightly based on weather and project schedule changes.

“The project team coordinated all waterway activities in advance with the U.S. Coast Guard to ensure they were meeting all permit requirements,” said City Manager Russ Blackburn. “The waterway closures are necessary to complete the bridge work over the North Fork of the St. Lucie River. We thank all residents for your patience during this time and all closures are in place for the safety of boaters.”

Boaters are encourage to check the project website,, or call the project hotline at 772-871-5176 for an update on the channel restrictions. All restrictions in support of this project also will be published in the future U.S. Coast Guard Local Notice to Mariners.

The Crosstown Parkway Extension Project will connect the existing Crosstown Parkway with U.S. Highway 1 at Village Green Drive. The project will provide numerous benefits to the community, including providing traffic congestion relief from Port St. Lucie and Prima Vista Boulevards and a new emergency evacuation route. Construction started in early January on roadway, drainage and utility activities. Project completion is anticipated in Fall 2019. The Crosstown Parkway Extension will provide a 6-lane divided roadway and trailhead, with the bridge being approximately 4,000 feet. It also will serve as a multi-modal transportation alternative with accommodations for automobile, bicycle, pedestrian and public transit.
