The House unanimously passed a bill Thursday that would allow the State Highway Administration or the Maryland Transportation Authority to raise the maximum speed on expressways and interstate highways to 70 mph.
The legislation, which now goes to the Senate, would not require either agency to raise speed limits. The current maximum is 65 mph. The bill would apply to parts of the federal interstate highway system and limited-access highways such as the Intercounty Connector.
David Buck, spokesman for the highway administration, said parts of such roads as Route 32 and Route 100 are also classified as expressways and would be eligible, but noted that the agency has set their speed limits below 65 mph. Any changes to current speed limits would be made only after traffic studies showed the roads could handle higher speeds safely, according to the agency.
