Reconstruction of the Twin Ports Interchange began earlier in 2022, but lately there have been some challenges.

Supply chain shortages are an issue. Unreinforced concrete pavement, is the most common, and cost-effective concrete used for light traffic. The concrete for the Twin Ports Interchange is very rare, Continuously Reinforced Concrete Pavement, which is the reason for the supply chain shortage.

Peter Marthaler, the Twin Ports Interchange Construction Manger, explained the bridges connected to I-535, will reopen in the fall of 2023.

That’s because they can start the Garfield Avenue bridge work this year yet, utilizing equipment that’s already in place. MnDOT said the bridge needs replacing, because it wasn’t designed to carry the weight of some of the cargoes coming into the port.

The northbound off ramp to 27th Avenue West will reopen this September 2nd. For intersection safety purposes three stop signs will be at both ends of 27th Avenue for intersection safety.

The demolition of the older remaining bridges won’t begin until October. Bridges connecting to interstate five thirty five will reopen in the fall of 2023 when the Garfield interchange is complete.

“We will continue to do year around construction. We will complete our substantial interstate work and our work on highway 535 in the fall of 2023.” Marthaler said.

Traffic lights will be installed next week to improve safety at Garfield Avenue. Currently, Garfield avenue is over capacity with traffic to and from superior, in order to help improve safety. It is recommended to use the bong bridge route, watching your speed and being considerate to other drivers.
