This week, crews completed demolition work and set curb forms at two locations in the Town Center: the NE corner of SE 27^th Street & 77^th Avenue and the SE corner of SE 28^th Street & 78^th Avenue. Due to contractor scheduling conflict, curb and ramp concrete pours were delayed and will not begin until next week. By the end of next week, both locations are expected to be open to the public

August 20, 2024

This project will upgrade 11 sidewalk curb ramps in the Town Center to meet current ADA standards. The contractor, NPM Construction, will start their removal and replacement work the week of August 26^th. The project is anticipated to last through November 2024, with work occurring between 7 am and 4 pm, Monday through Friday. Travel lanes may be closed intermittently during work hours, and pedestrian detours will be provided around each work area. To minimize disruption, the contractor plans to only have two ramps under construction at a time. Access to businesses will be maintained throughout construction.
