A section of the Gitchi Gami Trail at the Split Rock River reuses parts of the original north shore scenic highway.

Originally constructed in 1924, the old highway was bypassed way back in 1959 by construction of a new alignment a bit further from Lake Superior. Included in the construction was a culvert over the river, which replaced the original deck truss bridge. After being bypassed the old bridge was closed with permanent barricades.

Surviving sections of the old highway were left behind on either side of the old bridge as local roads (the road south of the river was made up mostly of a temporary connection built during the project, see plan below). Eventually, the old bridge was removed and the two roads fell into disuse (as seen in 1991 and 2003 aerial photos).

Plan showing the location of the temporary bypass built in 1959

The old highway finally found new life in the mid 00's, when the DNR used the surviving portions for construction of the Gitchi Gami Trail. A new footbridge was built on the site of the old highway crossing, allowing cyclists and pedestrians to enjoy the view of the mouth of the Split Rock River once seen by motorists.

Looking north from the ditch between Highway 61 and the Gitchi Gami Trail about a third of a mile south of the Split Rock River. The trail enters the old road grade at the top of the small hill ahead where the tree line between the road and trail starts.

At the top of the short hill, where the trail leaves the old highway to take advantage of a better view of Lake Superior (this was once the site of a gravel pit). A ruined portion of the old highway bypassed by the trail can be seen on the left.

Looking north across the Split Rock River at the new trail bridge, built where the old deck truss bridge used to be. One of the old footings is visible on the opposite bank.

Further along the trail, where it curves away from the current highway. The entrance on the left was used when the old highway was a local road.

The north end of the section of the trail that uses the old highway grade. On the left you can see the ruin of the old road where it once continued to connect to Highway 61. The trail on the right continues into Split Rock Lighthouse State Park.
