DDOT to Close Roadway on Kalmia Road Culvert Between East Beach Drive NW and West Beach Drive NW Starting Tuesday, October 29
The closures will remain in place approximately six months; pedestrian access will be kept open
(Washington, DC) The District Department of Transportation (DDOT) announced it will close the roadway on the Kalmia Road culvert located between East Beach Drive NW and West Beach Drive NW to vehicular traffic starting on or about Tuesday, October 29, 2013 after the morning rush hour.
The closure is anticipated to remain in place for approximately six months.
This closure was previously programmed to be implemented in late November to replace the deteriorated culvert at this location with a new bridge structure. However a recent inspection of the Kalmia Road culvert revealed additional deterioration has developed in the form of a “scour hole” due to rain storms over the past few weeks.
Although the roadway crossing at this culvert is still safe for pedestrian and vehicular traffic, DDOT is concerned that another rain event could cause further deterioration of the structure and therefore will be closing the roadway ahead of schedule to replace the culvert with a new bridge.
Scour Hole Definition: A “scour hole” is formed from the removal of foundation material due to a high velocity/energy stream occurrence. Scour holes are the major, most frequent reason for catastrophic bridge failures.
Proper detour signage will be in place to guide vehicular traffic around the closure. Motorists are advised to plan for additional travel time as traffic delays are likely to occur along the detour routes.
