Work crews today are changing the traffic signal configuration at Main and Ellicott for eastbound traffic, which is creating traffic jams in both the eastbound and westbound lanes of Route 5 and Route 63. Traffic is backing up for blocks at a time.

A worker said two sets of lights over Main Street's eastbound lane are being reconfigured, a new light pole with a set of lights on it has been set up for eastbound/southbound traffic turning onto Ellicott Street, and a new traffic control box is being installed.
