Old Alignment at Rock Creek

Located In: Rock Creek, Pine County.

Bypassed: 1954

Length: 1.15 miles (total surviving), .90 miles (drivable).

Also Marked As:

1934-Present (E/W portion only)

Until 1934

Over a mile of the original paved highway between the Twin Cities and Duluth survives at the town of Rock Creek in southern Pine County. The historic highway features a couple of old bridges, plus two short stretches of intact 1920's era concrete pavement.


The first paved highway at Rock Creek was completed in the mid 1920's. Work was completed in 1925 north of the creek (just north of current County Road 2 at the site of bridge 4141, see map above) and in 1927 to the south. The original pavement was 18 feet of concrete.

The stretch through Rock Creek featured an unusual number of bridges: four in just over mile. Three of these crossed the various channels of Rock Creek, while one was a railroad overpass. The bridges from north to south:

Bypass History

The original highway at Rock Creek was replaced in 1954 during the modernization of U.S. 61 between Rush City and Pine City. A heavy realignment was required to eliminate the two very sharp curves that had served to shift the highway a half mile in the east/west direction and carry it beneath a railroad overpass.

Current Status

The various stretches of the old highway met various fates after being bypassed.

Neither of the sharp curves at either side of the old rail overpass remain open. The west curve was closed and removed just after it was bypassed. The east curve remained in use, but was eventually abandoned. It survives in an overgrown state at the current intersection of 570th Street and Highway 70 with its original concrete pavement intact.

The east/west portion of the highway was taken over by State Highway 70 in 1954 (Highway 70 had been concurrent with U.S. 61 on this stretch since 1934). Because this stretch remained under state jurisdiction, it has received the most modernization, and has been rebuilt and repaved.

The portion north of Highway 70 remained open as a connection between Highway 70 and current County Road 61 towards Pine City. It was repaved and rebuilt in 1964, but has since been closed and abandoned. Large mounds of dirt have been piled on the road to prevent its use. The original bridge, no. 4143, still survives but is in poor condition.

The portion south of Highway 70 constitutes the longest surviving piece of the old alignment. Now marked as 570th Street, it is still in use as a local access road. The portion north of County Road 2 was formerly marked as Pine County Road 107 until bridge 4141 over Rock Creek was recently removed. Most of 570th Street has been repaved with a light seal coat. A short section south of County Road 2 still has its original concrete pavement exposed.

Looking west on Highway 70, just past the junction with Highway 361. The old curve to the north towards Pine City, now gone, was on the right side of the photo.

Looking south on the old connection between County Road 61 and Highway 70. The pavement here probably dates to about 1964 when this section was rebuilt.
