Project Description

The proposed project will reconstruct and realign the intersection of SE Main Ave and 20 St/21 St to pass under new bridges that will carry the BNSF and Otter Tail Valley Railroad tracks over the streets. The project will result in improvements to safety and congestion for vehicles, bicycles, pedestrians, and emergency services.

The project also includes the construction of new track (called a wye) that will allow direct northbound to eastbound and westbound to southbound train movements. Under existing conditions, trains must travel into the Downtown area, stop, and reverse direction to make these movements. The wye will eliminate delays at the Downtown crossings associated with trains backing up. Construction of the wye will require the closure of 1 Ave S near the wye track.
