Monroe Avenue Bridge

Monroe Construction began on February 16th on the new Monroe Avenue Bridge (according to reports, I actually haven't been out there lately). The present bridge has two sharp turns, so even though it was only built in 1986, it's being replaced largely, officials claim, for safety reasons.

Officials believe that removing the curve and straightening the bridge will improve safety, allow for an expansion of nearby baseball fields and parkland, and allow easier access to the shopping center for nearby residents. The developer, Potomac Yard Development LLC, will pay for the new bridge. Some proposed changes, such as a pedestrian ramp, will be paid for by the city.

Monroe2 It's not without controversy. Alexandria City Council member Andrew H. Macdonald wrote an op-ed arguing that the new bridge shouldn't be built until how best to increase bus, train and Metro ridership can be determined or until there is agreement on if the forecasted reduction in traffic will be large enough to offset many of the quality-of-life concerns expressed by residents. He dedicates an entire paragraph to cycling concerns in the area

Residents east and west of the tracks want to be able to bike and walk safely between George Washington Memorial Parkway, Del Ray and the Braddock Street Metro station. But now, instead of following a fairly direct east-west route, cyclists and walkers would have to follow a serpentine course to cross the new bridge. According to a bicycle and pedestrian watchdog group, many of the new intersections that will accompany this grid of new streets would be unsafe to cross; some trails would be too narrow, and crossing times would be much longer. So it's no wonder that there is still no consensus about how best to incorporate this important community benefit into the project. Advocates of biking and walking have asked the city to hire a firm that specializes in the design of such trails to ensure that both the disabled and able-bodied can navigate easily and safely.

Final_alignment The potomoc yard trail, a rail trail since it runs along an abandoned line of the old Richmond, Fredericksburg and Potomac Railroad, dead-ends just north of the site at Howell avenue. Any plans to build in this area should include a trail that continues along the rail line all the way to Braddock avenue. In addtion, a bike/ped bridge (built on the site of the old railroad trestle) should connect the trail to the W&OD railbed that still exists between Route 1 and Commonwealth Avenue.

The unfortunate thing about this bridge is that it's being built by the Potomac Yard Development Company. I would suspect that their first allegiance is to their investors so the bridge will serve Potomac Yard's interests and not the community's. Serving the community's needs is why - in theory - we have government in the first place.

The new bridge will have pedestrian walkways on both sides like the present bridge, but a little nicer.

The Potomac Yard Development site says of the park.

Potomac Yard Park will be a 24-acre linear park that will run parallel to the property between Potomac Avenue and the railroad corridor. This park will offer an ideal venue for the public to stroll along its paths or perhaps have picnics on its beautifully landscaped grounds.

Bridges: South Capitol and NE Branch

The South Capitol Street Bridge Study is complete. The following were completed as part of the study:

·  Identification, documentation and justification for protective buying as appropriate.

·  Study on river traffic, navigation, and bridge openings.

·  Contaminated soil and hazardous material site investigation.

·  Development of concept architectural, engineering, and alignment alternatives for four bridge types.

The bridge that exists now is definitely shoddy and while it has space on both sides for cyclists (pretty impressive for a bridge finished in 1941) it's not a very pleasant ride. The study site has four designs for the new bridge on it each with animations you can look at. Alternative one, the cable stayed swing bridge, even has an animation from a cyclists point of view. That's wicked cool. Predictably, it ends with a shot of the new baseball stadium. One can only hope that biking to the stadium will be easy and safe and that on the Anacostia side, riders will be provided with a safe connection to the Anacostia Trail, Suitland Parkway Trail and a trail built along the Shepard Industrial Spur. And, as long as I'm making a list, it would be great if they recognize that the stadium is a perfect place for a bike station and pedicabs.

In other bridge news, I've seen a pre-fabricated pedestrian bridge along side the NE Branch Trail near the Calvert Recreation Center (here). It looks like a construction crew left it there for work to be done later (because right now it doesn't bridge anything and is not fulfilling its purpose in life) but I have no idea if it it to replace the bridge over the small stream south of Paint Branch Parkway or if it is to be placed somewhere else entirely different. If you know, leave a message in the comments.
