The undeveloped areas of the Mississippi River gorge have a number of trails running though them, some marked, others just happen as people use a particular path over time. The area under the Dartmouth Bridge is very narrow, and is prone to rock slides. When the Dartmouth Bridge was rebuilt, a rock slide made the existing path unusable. To fix the problem, the City of Minneapolis Parks Dept. contracted to have a prefabricated bridge installed to run along the river shore. This would allow the trail to safely traverse the unstable area, and also make the trail safe at high water when there is almost no space between the rock face and the river. The catwalk, as it is called by the Parks Dept., runs from the East River Flats Park south to near the Cappelen Memorial Bridge at Franklin Avenue.

The east river bank saw a lot of construction work in 2008. The East River Flats Park was refurbished, with a new roadway and parking lot being installed, and a new park building being constructed. The City of Minneapolis replaced the bridge and retaining walls on the East River Parkway near Franklin Avenue and Bridal Veil Falls. Later in 2008, the City of Minneapolis Parks Dept. be work to rebuild the trails along the east bank of the Mississippi River. The goal is to establish a walking and bicycle trail along the river between the city limits with St. Paul all the way to Anoka County on the east side of the river.

Early in the morning on August 29, 2007, a drunk driver somehow ended up driving a 2 week old borrowed Cadillac Escalade onto the north end of this catwalk. The vehicle made it about 360 feet down the catwalk before it became hopelessly wedged between the railings. The driver then fled the scene. A towing company worked for several hours later that morning to remove the SUV from the pedestrian bridge. The $68,000 vehicle appears to be a total loss. The catwalk suffered some damage, mostly broken railings.
