Northern Tier Sec. 3 Maps 55-56 and L&C Sec. 3 Maps 49-50. Road closure 6/2023

The bridges of I-94 are being replaced where it goes over CR 139 about 6 mi. west of Glen Ullin. CR139 is closed at that point. Eastbound, from Hebron, turn right onto CR 90 towards I-94, ride onto on I-94 at exit 97 and then leave at exit 102. This put us on the other side of the closed CR139.  (Note: I-94 starts to become 1-lane per direction and both E and W split one side of the highway. Getting off at exit 102 got us off the road before the eastbound I-94 moved to the other side of the highway.)  Westbound, cyclists will have a harder time getting through the closure of CR 139. You certainly don’t want to be on I-94 east of exit 102 where there is one lane of each direction on one side of the interstate. And there is no option to get onto I-94 westbound at exit 102. We don't often recommend this, but it might be safest to hitch a ride in a pickup truck between Glen Ullin and Hebron. The bridge project is expected to run for 2 years.

Perfect opportunity to explore some of the dirt roads in the area.  Here is one possibility:

Another possibility is 40 1/2 St. from CR 139 and a right at the T onto CR 89.  That will take you back to CC 139 west of the bridge replacement location.

Might find yourself riding by beautiful fields of sunflowers.

Only 5.5 miles of dirt instead of 15.
But any dirt roads in western ND are very iffy in wet weather.

I believe it is important for ND DOT to retain access for cyclists thru the construction project.
I highly doubt that the parallel transcontinental railroad is shut down for 2 years.
Not to mention that federal transportation bills have a multimodality requirement in the funding.
