Nice Middleton Bridge Project - Construction


Timeline graphic - see bullets below:

Construction began in July 2020 with driving concrete foundation piles in the Potomac River.

Construction impacts on drivers and boaters are anticipated to be minimal because the new bridge is being built alongside the old bridge and the navigational channel will remain open and marked at all times.

The new bridge is expected to open in early 2023, at which time the old bridge will be torn down, a process that will carry into 2024.

USCG Fifth District Local Notice to Mariners – Potomac River Bridge Construction

July 13, 2020 – Mariners are advised that a construction contractor (SCM), on behalf of the Maryland Transportation Authority (MDTA), commenced construction on replacement of the Harry W. Nice/Thomas “Mac” Middleton Bridge over the Lower Potomac River, mile 50.0, between Newburg, Charles County, MD and Dahlgren, King George County, VA in June 2020, with completion estimated in December 2024. Work is scheduled from 7:00 a.m. to 7:00 p.m., Monday through Saturday, with limited work outside these hours for special operations. To facilitate bridge construction, temporary work trestles are being constructed north of the existing bridge extending outward from the Maryland shore approximately 200 feet and from the Virginia shore to approximately 320 feet. Dredging is scheduled to occur between mid-July and mid-September of 2020 near the Virginia shoreline for temporary construction access. Also, in mid-July 2020, pile driving for the new bridge will commence and progress to 52 pier locations across the river. In late summer of 2020, a concrete conveyor system will be constructed extending approximately 200 feet riverward from the Maryland shoreline just south of the existing bridge to deliver concrete via tug/barge to new bridge piers under construction.

A vertical clearance of 135 feet above mean high water and a horizontal clearance of 250 feet will be maintained throughout construction. In mid-July 2020, the navigation channel will be shifted approximately 115’ to the west and will be marked with navigation buoys during construction in additional to navigation lighting on the existing bridge. Construction on the new piers adjacent to the navigation channel will intermittently include barges along the outside edge of the navigation channel during daylight hours.

Marine equipment on site will include the multiple deck barges, crane barges, mooring anchors/balls, support vessels, and several large tug/push boats. All equipment will be marked and lighted as required by U. S. Coast Guard regulations. Mariners are urged to use caution when transiting the area and operate at minimum speed necessary to maintain safe course near the work site. Interested mariners can contact vessels KENNETH, GAIL, MAC, or CLYDESDALE via marine band radio VHF-FM channels 13 and 16 when actively working on the river, or call Jay Musser/Chris Brown of SCM at 443.392.8089 / 757.297.4796 for information.
