Two way traffic on Grassmere Avenue will be closed between Main Street and Bridlemere Avenue from 7 a.m. until 7 p.m. until Wed. May 25.
Grassmere Avenue was closed for an earlier construction project on the adjacent roundabout.
The DOT also said the detour from Main Street to Grassmere Avenue will direct traffic from Main Street to Corlies Avenue, Westra Street and Grassmere Avenue.
The traffic detour has been coordinated with the local police.
If the work is completed earlier than expected the roadway will reopen accordingly.
The existing crossing is being replaced with new concrete crossings and asphalt approaches.
