Ramps closed, commuter rail impacted in wake of Merrimack Valley explosions

HAVERHILL, MASS. (WHDH) - A series of gas explosions and fires in the Merrimack Valley is impacting travel Friday morning as several highway ramps remain closed and a commuter rail line has made changes to its route.

The off-ramps on I-495 northbound and southbound in Lawrence are closed as emergency crews continue a painstaking response to the thousands of homes in Andover, North Andover, and Lawrence that were impacted.

The Route 28, Route 114, Mass Ave., and Marston Ave. exit ramps are closed. Traffic on I-495 is still operating normally, and residents in those communities can still use on-ramps to get onto the highway, but access to those communities is restricted.

Additionally, the ramp from I-93 northbound and southbound to River Road is also closed.

The MBTA commuter rail Haverhill line is also impacted by the incident, as the line will only operate between North Station and Reading. Bus service will run from Haverhill and Bradford to Anderson/Woburn for inbound service, which is on the Lowell line.

Additionally, the MBTA is making parking at the Anderson/Woburn lot free on Friday.
