Temporary ACA Route Road Closures / Route 66 Section 1 Chain of Rocks Bridge Closed Summer/Fall 2026

« on: July 08, 2026, 02:11:19 pm »

The Chain of Rocks canal bridge in Illinois is closed for construction/repairs, which means there is no connection to the Old Chain of Rocks Bridge across the Missouri River now through early October 2026. Another option to cross the Missouri River is to use the McKinley Bridge Bikeway further south.

The Cave-In-Rock ferry is set to close indefinitely on July 1st, 2026 if they don't receive funding. The nearest detour is using the Shawneetown Bridge over the Ohio River. Check the Cave-In-Rock Ferry Facebook page for the most up-to-date information. If the ferry actually does close, we will work on creating an official reroute.

NW 150th St. is closed for bridge construction at the crossing of the East Branch Whitewater River (about 4 miles west of the US 77 crossing, south of Burns, Kansas). The quickest detour uses NW Shumway Rd., NW 140th St., and NW Hopkins Switch Rd., though these roads are all gravel.

There is construction just east of Ainsworth State Park that has closed the trail used for this route for 5 miles. There is a shuttle bus service between early morning and 6pm that takes peds/bicyclists between the Ainsworth exit 35 and the Bonneville exit 40. This construction should be complete soon, possibly by July 1.

The bike/ped bridge over Lake Pend Oreille into Sandpoint is indefinitely closed due to concerns of the bridge's structural integrity. Instead, it is recommended to ride US 2 between Newport and Sandpoint which has good shoulders the entire way.

Resurfacing and construction will significantly affect Highway 200 between Jordan and Brockway in Montana. Several portions of the roadway will be gravel during this time.

A map of the projects is posted here: https://www.mdt.mt.gov/pubinvolve/hwy200jordan/images/map-lg.png?v=2.

Bicycles are strongly recommended to avoid the area. In the past, some contractors ferried cyclists through on pilot trucks, but with two different contractors this year with different traffic control plans, coordination could be challenging.

A detour between Jordan and Glendive via Miles City can be found here: https://ridewithgps.com/routes/54269046.

The construction should be complete by 2028.

On Map 77 of Southern Tier Section 5, CC Camp Road (aka North Landing Road) in Chicot State Park is closed until further notice due to a bridge that did not pass inspection. Eastbound riders must use SR 3042 and SR 106. The route for westbound riders is unchanged.

There is also currently some construction on SR 106 that has the roadway reduced to one-lane. Ride with caution.
