1st Street Bridge Replacement and Round-A-Bout
Project Overview: (Bridge Replacement)
The 1st Street and North Folk river bridge at the southwest corner of Johnson Park was originally constructed in 1935 and reconstructed in 1983. The current structure is a four barrel box culvert with a structural bridge deck, sidewalks and bridge rails. The plan is to replace the current structure with a new 60 foot single span structure that will allow open movement on the river under 1st Street. The trail that currently crosses 1st Street on the north side of the bridge will be moved and run under first street along the river.
Project Overview (Roundabout):
The roundabout at 1st and Braasch was developed as part of the Braasch Avenue reconstruction project. During the community stakeholder meetings a roundabout was discussed as a way to control the three way intersection. JEO, the design engineer, gathered traffic data and conducted a traffic study to determine if a roundabout was adequate for the traffic volumes. Information was provided to the public about the feasibility of a roundabout at 1st during the City 1 & 6 year street plan development.
