This spring, work will begin to rehabilitate the pedestrian bridge over Old Georgetown Road, between Woodmont Avenue and Edgemoor Lane in Bethesda. Built in 1999, the bridge is about 90 feet long. It connects the Bethesda Place Development to the Bethesda-Chevy Chase Regional Services Center, the Metropolitan Apartments, an 1,100 space public parking garage, and other facilities.
The bridge will be cleaned and painted and needed structural modifications will be made.
Work to the approach portion of the bridge will include repairing the fascia girders and replacing the cladding and railing support system. The connection to the concrete building at the east end of the approach bridge will also be replaced. On the truss bridge portion, a new drainage system will be installed; concrete pavers will be replaced with stamped lightweight concrete; and the expansion joint at the interface between the truss bridge and the approach bridge will also be replaced.
The project is expected to take eight months to complete. Pedestrian access will be available at all times during construction.
The Montgomery County Department of Transportation’s Division of Highway Services (DHS) takes the lead during storms to clear roads of snow, remove downed trees and limbs and respond to problems caused by flooding. It may not be as well known that DHS also repairs some bridges. The bridge over Dry Seneca Creek on Montevideo Road in the western portion of the County was severely damaged last August during flooding caused by Hurricane Irene. Montevideo is classified as a rustic road, so the road and bridge must retain their historic character.
After the Division of Transportation Engineering developed a strategy to repair the bridge, a DHS crew that specializes in bridge maintenance set to work. They rebuilt natural stone walls leading up to the bridge, stabilized the old stone abutments, rebuilt the road embankment, reset guard rails, and resurfaced the approaches. To maintain its historic character, the Highway crew used native stone found near the bridge. This painstaking work took six weeks, and the road reopened to traffic late in October.

On August 1, the Department of Transportation’s Division of Transportation Engineering began a project to replace the 28-foot single span, steel beam bridge on White Ground Road, where it crosses over Buck Lodge Branch. The project will involve extensive stream restoration. Work is expected to be completed in spring of 2012.
The bridge will be closed to through traffic, but local traffic will continue to have access. The detour routes on Maryland Route 117 and Maryland Route 28 are marked with signs.
The 1967 Northwest Branch Beltway Bridge over the Anacostia River is showing signs of deck deterioration and must be rehabilitated in the portion between MD 650 (New Hampshire Avenue) and MD 193 (University Boulevard). This Maryland State Highway Administration project should be completed in fall 2012.
Work on the bridge begins this summer. No work can be done over the winter and the temporary concrete traffic barriers will be removed. Repairs will resume in spring 2012.
During construction, all eight lanes of the bridge will remain open during weekday peak travel periods, but lane widths will be reduced from 12 to 11 feet. Expect closures of one, two or three lanes overnight, depending on the time. Road shoulders will be unavailable until the project is completed.
About 230,000 vehicles use the bridge every day. Drivers are cautioned to remain alert and anticipate reduced speed limits, narrowed lanes and the presence of highway workers in the Northwest Branch Bridge corridor.
The Maryland State Highway Administration (SHA) will soon begin a two-year bridge rehabilitation project on the I-495 Northwest Branch Bridge between MD 650 (New Hampshire Avenue) and MD 193 (University Boulevard) in Silver Spring. The existing structure was built in 1967 and its deck is showing signs of deterioration. Construction will begin this spring and should be completed in the fall of 2012, weather permitting.
Repairs include replacing portions of the existing concrete bridge deck. SHA will also replace the traffic barriers, install new concrete to resurface portions of the bridge deck not being replaced, and resurface the approach roadway once bridge work is complete.
Crews will manage construction in eight phases, incorporating multiple lane shifts for the duration of the project. Pattern changes include a temporary traffic split around the work zone and temporary lane shifts on both sides of I-495.
Beginning in early spring, the Montgomery County Department of Transportation’s (MCDOT) Division of Transportation Engineering will rehabilitate the bridge that carries three westbound lanes of East Gude Drive over the railroad tracks owned by CSX and Metro (Washington Metropolitan Area Transit Authority). An inspection of the bridge found that the concrete deck and substructure had deteriorated. The bridge carries about 20,600 vehicles a day.
During construction, which should take about a year to complete, two lanes of westbound traffic will be maintained at all times. Rehabilitation activities will include removing the existing bridge deck, cleaning and painting steel beams, replacing the bearings, and replacing parts of the abutments and piers. Construction will occur Monday through Friday between 7 a.m. and 5 p.m. , with some Saturday work.
The cost of the project is $1.8 million. More information about the project is available on the MCDOT’s website.
Work has begun to replace the Clarksburg Road Bridge and rehabilitate the deteriorated concrete bridge abutments. The project is part of the approved Damascus Master Plan. The existing concrete and steel superstructure will be replaced with a new concrete bridge and 450 feet of the approaching roadway will be reconstructed. The bridge will have two 11-foot wide travel lanes and four-foot wide shoulders on each side of the roadway, for a total width of 30 feet that will allow for on-road bicycle traffic.
One lane of the bridge will be open at all times to allow through traffic while work is completed. Traffic will be controlled by a temporary traffic signal that will be installed prior to the start of construction. Clarksburg Road will be open to two-way traffic throughout construction.
The project is expected to be completed in the summer of 2011.

The Division of Highway Services has begun refurbishing the bridge on Goldmine Road. This work includes re-decking and repaving the bridge and replacing barriers along the bridge and its approaches. A detour will route vehicles along Chandlee Mill Road, Brooke Road and New Hampshire Avenue.
The Division of Highway Services is completing a bridge improvement project on Huntmaster Road in the Laytonsville area to redeck and repave the bridge, as well as replace the guardrail along the bridge. The bridge has been closed for about four weeks during the construction project.
Montgomery County Executive Isiah Leggett, local officials and residents celebrated the reopening of the East Deer Park Drive Bridge in Gaithersburg on August 24 after the completion of urgent repairs this summer. The historic bridge, constructed in 1946, had deteriorated with age.
The Montgomery County Department of Transportation’s (MCDOT) Division of Transportation Engineering conducts routine bridge inspections. In 2008 it found that the timber supports for the bridge’s steel beams were in an advanced state of decay and needed to be replaced within 12 months. Because of the need to act quickly and the location of the bridge over railroad tracks, the project presented some unique challenges. Temporary steel beams placed across the bridge suspended hangers that lifted the superstructure and allowed access to the bridge supports while they were replaced. MCDOT also resurfaced the bridge deck with asphalt.
MCDOT operates a model bridge inspection, repair and maintenance program for the county’s 319 bridges. Of these bridges, 199 are defined as long-span -- more than 20 feet long -- and 120 are short-span --between six and 20 feet in length. Inspection schedules for bridges are specified by Federal guidelines. Long-span bridges are inspected every two years with the Federal government providing funding for the inspections. The County pays for inspection of short-span bridges, which is done every four years. Following each inspection cycle, MCDOT initiates repair or replacement of priority bridges. The County also funds minor rehabilitation of bridges and preservation efforts that maintain bridges by painting the steel components.
