Fewer traffic tie-ups on York Road are expected after today's opening of a new exit off Interstate 83.
Shortly after evening rush hour, state officials are scheduled to open the 1.5-mile-long extension of Warren Road from York Road to I-83 in Cockeysville.
The $17.5 million project includes a partial interchange with the highway and a 350-space park-and-ride lot.
This latest interchange will permit motorists to travel north on I-83 and then east on Warren Road, or west on Warren Road and south on I-83.
Liz Kalinowski, a State Highway Administration spokeswoman, said traffic will be allowed on the extended Warren Road after opening ceremonies are wrapped up, probably after dark.
Warren Road is midway between Padonia and Shawan roads.
The new exit should relieve much of the congestion at the notoriously busy York Road-Padonia Road intersection, she said.
