Monroe County’s 1st Street and Bertha Street Roadway and Drainage Improvement Project in Key West is scheduled in phases through July 2022. The work will consist of reconstruction and resurfacing the two roads, installing a new stormwater collection system on Bertha Street, and rehabilitation of the existing stormwater collection system on 1st Street. The County partnered with the City of Key West to include reconstruction of existing sidewalks, construction of additional sidewalk and ADA-compliant curb ramps, and installation of landscape cut-outs. The design calls for reconstructing the roads using an asphalt base instead of typical limerock to minimize deterioration due to high groundwater and future sea-level rise impacts.

Due to the underground work and full-depth road reconstruction, there will be lane closures and detours for extended periods. Work will begin on Bertha Street from Atlantic Blvd to Venetia Street on the westside of the road/existing southbound lane. Southbound traffic will be shifted to the northbound lane at Venetia to Atlantic, then shifted back into its regular lane at Atlantic Blvd. Northbound traffic will be detoured at Atlantic to George Street to Venetia and back onto Bertha. Eastbound traffic on Atlantic turning left onto Bertha will be detoured to George Street to Venetia and back onto Bertha. There will be signage, including “DETOUR TO NORTH BERTHA” with an arrow.

As the project phases progress, additional information about lane closures and detours will be shared as it becomes available at Crews will make an effort to minimize disruptions. Work areas will be accessible to emergency vehicles, local traffic, and residents. 

The project is managed by Monroe County through RS&H and is partially funded by a Florida Department of Transportation Small County Outreach Program grant. The County has coordinated with the City of Key West and Florida Keys Aqueduct Authority for various infrastructure improvements to happen concurrently with the project.
