The new arch bridge in Hastings that will cross the Mississippi River is planned to start construction next summer, but a few preliminary safety precautions started last week.
The bridge, which will be Minnesota's first free-standing, above-deck arch bridge, will ease traffic congestion and will do so artfully.
According to the Star Tribune the arch bridge will light up at night and have the longest arches inNorth America at 545 feet, transportation officials said.
The bedrock was tested last week to ensure could handle the 11,500-ton load expected from the bridge.
Other tests started Monday to assess pile strength capacity for some of the piers of the new bridge. Small explosions are expected to last for the next to weeks and are constricted to daylight hours, the Pioneer Press reported.
