Work has gotten underway again on infrastructure upgrades in the Gobbi, Main, and Orchard Street projects. On East Gobbi, water main construction between Orchard Avenue and Main Street is expected to take about six weeks. On Main Street, water main tie-ins are finished, and concrete crews will build new sidewalks and ramps on both sides of Main Street. That will also be done in about six weeks. West Gobbi’s work has been rescheduled for early summer.
