If you have an E-ZPass, crossing the Francis Scott Key Memorial Bridge is going to get a bit easier. If you're paying cash, maybe not.

In response to increased E-ZPass use, the Maryland Transportation Authority is changing its lane configuration at the Key Bridge. The change will cut the number of lanes with toll collectors and increase the number that take E-ZPass only.

Currently there are three E-ZPass-only lanes in each direction and three that take both the passes and cash. After the change is implemented this weekend, there will be four E-ZPass-only and two pass-or-cash lanes each way.

The changes will also group the E-ZPass only lans to the left and the mixed-use lanes to the right. The change will create an E-ZPass-only lane on the right side of the toll plaza that trucks can use.

The authority said the changes will improve traffic flow and allow motorists to get to the right lanes more efficiently. The agency said 70 percent of vehicles on the bridge now use E-ZPass.

Obviously, this means fewer toll plaza lanes will be staffed by human collectors. For cash customers, that can only mean more waiting. However, the Key Bridge is one of the least congested Maryland toll facilities so maybe it won't be too bad.
