I rode from Pentagon City to downtown DC around 1:30 today via MVT and George Mason bridge.
Heading east: the Crystal City tunnel was completely clear including the entry downhill. The flyover bridge by the airport had packed snow on the right hand side with lots of melting runoff which will surely freeze overnight. The MVT was completely clear of water/snow for the rest of the way to the GM bridge and into DC. Lots of salt everywhere though.
Heading west: there is a puddle under the second to last light going into the Crystal City tunnel which will surely freeze overnight so keep an eye out for it. The flyover bridge by the airport was clear on the southbound lane. On the way home, I took the pedestrian bridge from L’Enfant Plaza to Hain’s Pt; all clear as well including Hain’s Pt.
