The Town of Lyons announced that a major project milestone occurred in mid-February when concrete girders were set in place on the new bridge supports. Bridge girders were delivered to the work zone on 2nd Avenue at St. Vrain Creek during the evening of Feb. 16 and early morning of Feb. 17.
This work must be performed overnight due to travel restrictions placed on the trucks carrying the oversized loads. Nine girders were delivered to the site and each girder is 140 feet long. As the girders arrived, they were removed by crane and placed on the new bridge abutments. Temporary lighting was used overnight at the bridge site and along the delivery route.
Safety is the priority. Flaggers instructed traffic along the delivery route; and some streets were closed to drivers and parking.
The project is on schedule for completion in spring / summer 2021.
This schedule is weather-dependent and the schedule is subject to change.
This project will replace the existing 2nd Avenue bridge over St. Vrain Creek to better accommodate future flood events. The bridge is closed to all traffic, including vehicle, pedestrian, and cycling, through May 2021. The 2nd Avenue alley access from 2nd Avenue is also closed.
