In order to install bridge deck and girders for the new 27th Avenue West Bridge, the northbound lane of Interstate 35 will be closed two days beginning Friday.

Beginning at 8 p.m., Friday, northbound I-35 will close near 27th Avenue West, rerouting traffic up and back down the 27th Avenue West ramps. Closures are anticipated to last through Saturday evening, a Minnesota Department of Transportation news release said.

The 27th Avenue West Bridge reconstruction is one of the first portions of work related to the $343 million Twin Ports Interchange reconstruction project.

Work on the Twin Ports Interchange reconstruction project is expected to last until 2024, with major construction completed in 2023.

The project is designed to improve safety and freight movement and replace aging, weight-restricted bridge infrastructure.

All exits are moving to the right, and new construction will eliminate blind merges common throughout the existing ramps located in the Lincoln Park neighborhood of Duluth.
