In addition, City inspectors have identified further issues with the sewer line installation by the Alere development which require immediate corrective action. The Alere developer has been instructed to address these deficiencies promptly.

As a result, the closure of the westbound lane will be extended throughout the month of June. While these delays are frustrating for all parties involved, the City’s top priority is the safety of our community.

To help ease local traffic flow, we are pleased to announce that Pine Avenue has been fully reopened between West Preserve Loop and Homecoming Drive. Furthermore, access to East Preserve Loop south of Pine Avenue is expected to reopen on June 15th.
