Route 29 Has Flooded Out
The bridge carrying Route 29 over Northwest Branch is covered in water. The torrential rain we have had over the past two days has caused Northwest Branch to breach its banks and flow over the bridge in Burnt Mills by the old WSSC buildings. This has not happened since June of 2006 (I'm almost certain). As most people know, Route 29 is a major commuter route in eastern Montgomery County. When it gets closed in both directions, traffic in the whole area feels the ripples effects. Traffic can be expected to be horrible in Four Corners (worse than it usually is) until it reopens.
A closing like this highlights the impact Northwest Branch has on eastern Montgomery County as well. Only 5 roads cross the creek between the Prince George's County line and Colesville. They are New Hampshire Avenue, Piney Branch Road, the Beltway, Route 29, and Randolph Road. When a major road like Route 29 gets closed, the other roads have to carry the extra traffic. Route 29 in the vicinity of Burnt Mills carries around 55,000 vehicles per day. With the bridge flooded, most of that traffic will be shifted to the Beltway, as it is the next closest road crossing of the creek (1.5 miles south of Burnt Mills).
The last time this happened, the road was closed for a couple days while the sediment (mud from the creek) was cleared from the bridge. The bridge also had to undergo a structural evaluation to make sure it was not damaged by the flood waters. The June 2006 storm flooded the bridge at night, and a car was washed off the road because the driver did not notice the flood in the dark until his vehicle was in the water.
Sadly, the motorist was killed after his car was washed down the creek. His body was recovered in Prince George's County (where the creek joins Northeast Branch to form the Anacostia in Bladensburg) the next day, but the Prince George's County Police failed to inform Montgomery County of the discovery. Because local police were unaware the body had already been found, multiple law enforcement agencies held a massive search of the stream valley for the missing motorist during the ensuing days. This search involved police helicopters, search dogs (Bloodhounds) and dozens of police officers. The incident helped improve inter-agency communication among local police and fire departments, so there was a silver lining to the tragic death.
Thankfully, this flood occurred during the day, so no motorists unknowingly drove into the water. Police currently have Route 29 closed in both directions at Southwood Drive going northbound, and Lockwood Drive going southbound, and they are not allowing anyone to get close to the water on foot. Remember, other roads in the county may be flooded, even ones that cross small creeks and streams. If the road appears to be flooded: Turn around. Don't drown. Even water a couple inches deep can wash a car off the road. If you come across a road that is flooded, but not closed down already, call the police right away so they can close it before someone else drives into the water.
The rain is expected to end tomorrow morning.
