Welch Rd is now a one-lane, one-way road going West from Quarry to Pasteur Drive. This change will be in effect for two years. We thank you for your patience regarding this significant change and ask that you please adjust your driving route accordingly. South Pasteur Drive is now a two-way two-lane road. North Pasteur Drive is closed between Blake Wilbur Drive and Sand Hill Road.
K-Rail will remain in place on the inboard side of Quarry Rd (between Welch and continuing up to the Quarry Extension near the turn to the Emergency Department) in order to facilitate ongoing utility work. This reduces Quarry to a two lane, two direction road during this time. Access will be maintained to the Emergency Department at all times.
Water tie-ins will occur along Welch Road beginning Monday, 3/5. Temporary water shut downs will occur during this time. All shut downs have been coordinated with individual properties and tenants. This work will not impact the hospitals' utilities.
Work will continue to install a new hot water line on Quarry Road. This work will take place in Quarry Extension. Access to Receiving and to the Emergency Department will be maintained at all times via flagmen.
Work to install a new chilled water line will continue on Welch Road.
