After months of construction delays on Route 128, the Department of Transportation opened a fouth travel lane on southbound 128 between Westwood aand Randolph on Nov. 14.

The additional lane means there’ll be no more driving allowed in the breakdown lane.

This addition is the first of three lane segments to be added along 128.
