State transportation officials said they are studying the use of tolls on two Montgomery-area highways to combat congestion in the rapidly growing region, and hope to meet with the public about the potential projects in the fall.

Doug Simmons, deputy administrator with the State Highway Administration, said the state is evaluating how tolls could ease traffic flow on parts of Interstate 270 as it runs from I-370 North into Frederick County and also on the west side of the Capital Beltway.
