Various daytime lane closures are planned on I-495 north Tuesday through Thursday as bridge construction continues.

The Massachusetts Department of Transportation reports there will be single left lane closures between exits 48 and 49 Tuesday and Wednesday, July 14 and 15, from 6 a.m.-2 p.m. daily. Closures are necessary for median earth work.

There will also be a single right lane closure on I-495 north, between exits 48 and 49, on Thursday, July 16, from 6 a.m.-2 p.m., for pier protection barrier work.

Work is weather dependent.

The new bridges, being constructed at a cost of $102 million, are designed to last 75 years as opposed to the existing bridges built less than 60 years ago. Officials say the goals are to eliminate “constant emergency repair work,” improve roadway safety with full-width breakdown lanes and provide a dedicated exit lane on the northbound bridge for exit 49, near Westgate Center.
