Duluth's first protected bike lane open for traffic The City of Duluth's first protected bike lane is open for traffic. It replaces the portion of the Cross-City Trail that was closed during the Twin Ports Interchange Project. | Photo: WDIO WDIO Created: July 16, 2021 03:26 PM The Twin Ports Interchange Project has disrupted several aspects of the Lincoln Park neighborhood, from traffic to residential properties. A portion of the Cross-City Bike Trail was also shut down when construction began, but thanks to funding from the Minnesota Department of Transportation, a new bike lane is up and running in its place. "This closed a huge gap for when the Twin Ports Interchange is under construction," said the project's lead engineer, City Voigt. "We have a real hard time getting around down here, and having this corridor for alternative transportation is really huge for the city."
