Engineers and subcontractors from B&L will be on site Tuesday, December 9th at 8:00 a.m. and again briefly on Wednesday, December 10th to collect pavement cores and conduct subsurface investigations.  This work will require short, temporary lane closures (one block or less) with alternating one way traffic on December 9th.   Beginning Wednesday, December 10th, subcontractors will also start CCTV inspections of the sanitary sewer system along 25th Street.  This portion of the project is expected to last two to three weeks, possibly longer, depending on the condition of the pipes.  During this time, residents should expect traffic diversions, including lane shifts and short lane closures with alternating one-way traffic while crews work in the roadway and access manholes.  If you have any questions, please do not hesitate to contact City Hall.  Thank you for the patience and cooperation.
