The Dedham Square Improvement project will move forward with full depth roadway reconstruction on Washington and High streets.
Work will be conducted primarily at night from Sunday through Thursday, with hours being from 7 p.m. to 5 a.m., according to a statement released by project organizers.
The first priority will be full depth roadway reconstruction on Washington Street from School Street to Crossfit Craic at 355 Washington Street.
Work will consist of removing existing asphalt and underlying soil, placement of base course gravel, grading and compacting, and then installing two layers of asphalt pavement.
The final layer of asphalt will be installed at a later date, according to the statement.
The road will be closed while construction takes place and detours will be established. No on-street parking will be allowed at night within the work area. All vehicles must be moved from the work area by 6 p.m.
Next, work will continue on High Street from the Route 1 overpass to Eastern Avenue and on to Eastern Avenue up to the CVS. The work will be the same as the section of Washington Street.
The section of Washington Street should be completed by Tuesday, and then the contractor will move on to High Street and Eastern Avenue
In both cases, the work area will be smooth graded and compacted prior to the end of each shift and open to two-way traffic during the daytime.
Temporary pavement markings are expected to be installed on High Street from Court Street to Washington Street on Wednesday or Thursday night. The road is not anticipated to be closed during this work, but parking will not be allowed on the street at night within that work area.
The contractor’s landscaper will also be in the Square to replace plantings and trees that did not survive the winter. NStar will also continue to replace utility service on Washington and Harris streets.
