This morning the fire trucks came to the Chevy Chase bank building on the corner of East-West highway and Wisconsin Avenue (Route MD-355) in Bethesda, MD. They closed off two northbound lanes on 355 (out of 3) and two westbout lanes on East-West (again, out of 3). That really causes traffic problems. I didn't see anything obviously wrong although they did have the hoses out and connected to the buildings standpipe. As I am writing this, they are packing up the hoses and getting ready to go home, so lanes should re-open soon. I didn't see anything on the WTOP traffic page about it but it was the lead story on the traffic report I heard.
