Update, 9:52 a.m.:

All lanes on westbound Route 50 have reopened.

Original post:

Traffic on westbound Route 50 is delayed for several miles following an accident near Bay Dale Drive, about five miles from the Bay Bridge.

A tractor-trailer overturned in the roadway Thursday morning and temporarily blocked all westbound lanes. The left lane is now getting by slowly.

Delays extend about nine miles heading into Annapolis. Drivers are urged to use caution and choose an alternate route, if possible.
