US 0001 BELAIR ROAD BRIDGE 0300300 OVER GUNPOWDER FALLS
Project Name:
US 1, Belair Road

Location of Project:
BRIDGE 0300300 OVER GUNPOWDER FALLS

Description:

In 2019, MDOT SHA will begin a project to rehabilitate the bridge carrying US 1 (Belair Road) over Big Gunpowder Falls and pipe on US 1 over the Big Gunpowder Falls trail.

The existing bridge is a five-cell metal pipe arch, and a separate pedestrian/equestrian metal pipe underpass beneath US 1 is located to the north of the river. All six arches/pipes have extensive corrosion and need to be repaired.


The project will provide a concrete liner around the inside circumference of each of the water openings. For the trail opening, a smaller metal pipe will be placed inside and the gap between the new and existing pipes will be filled with grout.


The project will also stabilize the trail leading from the parking lot under US 1, using concrete blocks. Trails over the Gunpowder Falls (parallel to US 1) will be stabilized using gravel. These stabilizing improvements will reduce the amount of water and mud that builds up on them during a rain storm. Additional improvements to the park include replacement of two gates and re-staining the existing timber traffic barriers in the parking lots.

All lanes of traffic will be maintained on US 1 during peak travel times and only the shoulders on the bridge will be closed. Temporary lane closures will be used during nonpeak travel times.

The main parking lot to the Big Gunpowder State Park along US 1 northbound will be closed for the duration of the project. The supplemental parking lot located further east of the main parking lot will be open, as well as all trails east of that parking lot.


The project will be completed in two stages. During stage 1, the trail under US 1 and trails over the Gunpowder Falls (parallel to US 1) will closed for approximately 3 months. During this time, access cannot be safely allowed to the west side (west of US 1) of the Big Gunpowder State Park. During stage 2, all trails will reopen while the remaining arches over the river are rehabilitated. The main parking lot will remain close for storage of materials and equipment. During this stage, temporary scaffolding with debris shields on top will be placed along trails over the Gunpowder Falls (parallel to US 1) to keep them open.
 
Scope:
In early summer 2019, the Maryland Department of Transportation State Highway Administration (MDOT SHA) began a new $3.6 million project to rehabilitate the bridge carrying US 1 (Belair Road) over the Gunpowder Falls and the trail tunnel underneath US 1 within the Gunpowder Falls State Park – Central Area.

The existing US 1 bridge over the Gunpowder Falls (also known as the “Big” Gunpowder Falls) is a corrugated metal pipe arch bridge. The arched trail tunnel underneath US 1 north of the Gunpowder Falls is a metal pipe arch underpass. While the US 1 and the trail tunnel are safe for travel, MDOT SHA is proactively repairing the metal pipes on these structures due to corrosion.

MDOT SHA’s bridge rehabilitation project will provide a concrete liner around the inside circumference of each of the pipe water openings. For the trail tunnel, a smaller metal pipe will be placed inside the existing pipe and the gap between the new and existing pipes will be filled with grout.

The project also includes enhancements to the State Park, such as stabilization of the connector pathway from the main State Park parking lot to the trail tunnel, and stabilization of the trails along the US 1 bridge. These stabilizing improvements include placement of brick and gravel to reduce the amount of water and mud that builds up on the trails during rainstorms. Other improvements to the State Park include replacement of two parking lot gates and re-staining the existing timber traffic barriers in the parking lots.

STATE PARK VISITOR ADVISORY:

The project will be done in two stages. During both stages of work, the US 1 bridge over the Gunpowder Falls will remain open to all traffic.

The driveway to the Gunpowder Lodge restaurant and the MDOT SHA Park and Ride lot along southbound US 1 will be open at all times for restaurant customers and US 1 commuters.

During construction work, there will be temporary single lane closures along northbound and southbound US 1 between Miller Road and Sheradale Drive during off-peak travel hours.

As of June 17, the trail bridge crossings along northbound and southbound US 1 over the Gunpowder Falls, and the tunnel crossing underneath US 1 are closed for approximately seven months.

The trails west of US 1 will remain accessible to park visitors from the Park and Ride lot along southbound US 1.

As of August 1, 2019 DNR has closed the Gunpowder Falls State Park parking lot along northbound US 1 just north of the bridge. The lot is temporarily closed to visitors until further notice. The parking lot along US 1 north near the Little Gunpowder Falls is open.

On street parking is prohibited on northbound and southbound US 1 in the vicinity of the bridge work zone.

MDOT SHA’s contractor is Marine Technologies, Inc. of Baltimore, Md. Weather permitting, the project will be complete fall 2020.
