1st Street and Bertha, Key West 

Monroe County’s 1st Street and Bertha Street Roadway and Drainage Improvement Project in Key West is currently underway. The work consists of reconstruction and resurfacing the two roads, installation of 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 as well as installation of landscape cut-outs. The design calls for the reconstruction of the roads using an asphalt base instead of typical limerock in order to minimize deterioration due to high groundwater as future sea-level rise impacts are felt.

Due to the underground work and full-depth road reconstruction, there will be lane closures and detours for extended periods of time. Work will begin on Bertha Street from Atlantic Blvd to Venetia Street on the west side of the road/existing southbound lane. Southbound traffic will be shifted to the northbound lane at Venetia to Atlantic then shifted back into their normal lane at Atlantic. Northbound traffic will be detoured at Atlantic to George Street to Venetia and back onto Bertha. Eastbound traffic on Atlantic that wants to turn left onto Bertha will be detoured to George Street to Venetia and back onto Bertha.

Crews will make an effort to minimize disruptions and make the work area accessible to emergency vehicles, local traffic, and residents. 

The project is being 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. 

Estimated Date of Completion: The project will be done in phases and is tentatively scheduled for final completion in late fall 2022.
