Note that this detour is no longer recommended, and it was only posted for use during when the road was impassable (late 2015). There are now (2019) a couple short, crude trails over talus that cyclists can hike their bikes though to continue on the road.


From Coldspring local Susan Butler:

"Texas State Hwy 150 between Punkin and Coldspring is currently under construction. On, it gives an expected completion date of 7/31/2019, which isn't going to happen! They are way behind. I have planned two alternative routes on One is named "Hwy 150 Alternate" and is suitable for hybrid and mountain bike tires only as it uses forest service roads. It is also very remote, but beautiful; it meanders through the National Forest.

The other route is named "Hwy 150 Construction Bypass", and follows paved roads. I will warn you, though, that the intersection of Hwy 150 and Hwy 1725 is fairly dangerous! Cyclists should approach that intersection with caution.

Road tires CANNOT ride on the section of the road currently under construction. The road is torn up and is even very bumpy to drive on (and I have a 4WD truck)! Thanks!"

A map of detours that are being implemented for the Arkansas High Country Race is available here:

Some comments: Mapped routes in red, flood detours in blue. Note that this map doesn't include detours for the Dardanelle to Conway segment on the South and Central Loops. The race does not follow this route. Also, a few detours are not flood related, but were implemented for closer access to services. These are in Russellville, Eureka Springs and Mountain View.

Again, make sure to check status reports provided in the links of this thread. The flood situation is rapidly changing.


East of Rawlins, a 6-mile stretch of I-80 between Walcott Junction and Sinclair is under construction through Oct 2019. Traffic is reduced to 2 single, head-to-head lanes, with speeds of 65 mph. These made for nervous conditions for cyclists recently. Exercise caution along this stretch.

For info and status reports:

No easy detours exists through this area. Cyclists who can handle unpaved roads could depart the TransAm south of Walcott Junction at Riverside, and head west on SR 70 up into Medicine Bow National Forest, crossing the divide at Battle Pass, and then north on (mostly) unpaved Sage Creek Rd. into Rawlins. This detour is 78.5 miles long (compared to 58.8 mi on TA), includes steep climbing on sometimes narrow mountain highways and about 45 miles of gravel/dirt surfaces, no services except camping, and a visit to the famed Aspen Alley. Here is the route:

Also, as of 5/30/19, much of the Arkansas River Trail around Little Rock and North Little Rock is impassable due to flooding. The route primarily uses the trail system to access the city from the main South Loop. Any travel between Little Rock and Pinnacle Mountain State Park (south side of river), or Little Rock and Conway (north side) will require detours. I will post any detours as we are made aware.

The inaugural Arkansas High Country Race on Jun 8 will still be happening, but several detours will be in place to avoid flooded areas.
Some pics of the flooding are posted on the event FB page here:


There are currently several road closures due to flooding in the Arkansas River Valley and tributaries on the South and Central Loops. The route between Dardanelle and Conway in particular has at least 4 road closures, including the Arkansas River bridge on SR 60 at the Perry/Faulkner County line near Toad Suck. No detours have been posted. The conditions are changing rapidly, so be sure to check the below links for status:

US 95 in Idaho is undergoing multiple construction projects at various locations along the TA Sec03 route. Here is a link to ITD projects and info:

A brief overview-
Map #28: Between Race Creek Road (near Riggins) and Slate Creek Road (13 miles north of the Riggins area). The road is being repaved. There is work on the shoulder. The roadway is reduced to one lane. Expect delays. Look out for flaggers. Expect 15 - minute delays. Until July 31, 2019 at about 8:00PM MDT.

Map #27: Between Smokey Boulder Road and Hazard Creek Road (12 miles north of the New Meadows area). Bridge construction work is in progress. The roadway is reduced to one lane. There is a width limit in effect. Width limit 14'0". Until November 18, 2019 at about 11:59PM MDT.

Map #26: Between East Fork Road and Old Highway (8 miles north of the Council area). Bridge construction work is in progress. The roadway is reduced to one lane. Look out for flaggers. Look out for temporary traffic lights. There is a width limit in effect. Speed restrictions are in force. Width limit 12'0". Speed limit 35 MPH. Until November 1, 2019 at about 7:00PM MDT. *Note that the unpaved Weiser River Trail from Cambridge to Tamarack is a detour option around this project. See for more info.

Make sure to plan accordingly as travel along this stretch will be slow all summer. Check the ITD link for status updates, and feel free to post here any new info.

The Mississippi River Trail is temporarily closed directly upriver from Norco due to opening of the Bonnet Carre Spillway to accommodate rising river levels.

The suggested detour (using ST 05 narrative and mileages) begins at SB turn G 25(40): instead of turning right onto River Rd., continue straight on SR 628 (which has decent shoulders) 2.6 mi. N to US 61. Turn right onto US 61 (also good shoulders) and follow 2.2 mi. E to  Apple St./SR 48. Turn right onto Apple St./SR 48 and follow 1.4 mi. S back to River Rd. and an access ramp to the levee trail. A Google map of the detour is here:

Locals have stressed that flooding may be a problem this year, so currently there is no timeline for the levee path to reopen. Check the below links for status updates:

CR ZZ in Wrightstown was closed 9/4/18 between High St. and Dock St. due to rising water on the Fox River.

The closure is weather dependent and could change at any time, but still closed as of 9/17/18. There is no detour posted but an option exists by skirting the tributary of Fox River from High St, to CR D, to E. New Rd. and Outagamie Rd. and back to CR ZZ further west. See this map for more details.

Here is the Inciweb post for the Howe Ridge Fire:

The northern Lake McDonald area (Lake McDonald Lodge, North Lake McDonald Road, and the Avalanche and Sprague Campgrounds, private residences) has been evacuated and is completely closed. The Going-to-the-Sun Rd. is closed from near Apgar to Logan Pass, though it remains open from Logan Pass to St. Mary.

Here is a number for more fire info: (406) 888-7077

Here is the Inciweb post for the Boyds Fire:


From WSDOT: Closure due to Boyds Fire on SR 20 from milepost 337 to milepost 342, Inchelium Rd to SR 395 - Barneys Jct. (intersection of US 395 & SR 20), beginning at 5:22 pm on August 11, 2018 until further notice. This location is west of Kettle Falls, on the west side of the Columbia River. No detour has been posted, and cyclists looking to cross the river must travel off route far to the north or south for any options.

The shortest option (EB) involves heading south on Inchelium Rd. to the ferry crossing between Inchelium and Gifford on the east side of the river, then taking SR 25 back north to Kettle Falls, as seen in this map: This detour is ~53 miles long. Take caution, as traffic may be fast, the roads windy, and limited shoulder space available on these roads that may not see much cyclist travel. Reverse the directions for WB. There are limited services in both Inchelium and Gifford, and an NPS campground in Gifford:

Here is the website for the ferry:

Barring the ferry, a northern option involves riding US 395 and Northport Flat Creek Rd. to Northport, then returning on SR 25: a detour of over 65 miles.

Here is the Boyds Fire Information Center phone number 509-481-7064. There doesn't seem to be incident website that is being maintained at this time.

If anyone else has info about getting around this closure and across the river, I implore you to share it here. Thanks!

More info on the obstacle:

The trail meets a earthen berm, the other side of which falls away into the pit. See pic below. At least one rider reported they walked their bike down the berm and crossed the pit. The trail does resume on the other side, which is also shown in pic below.

We have received a couple rider reports of the Elk Valley Trail dead-ending at a gravel pit about 4 miles north of Hosmer, BC. We are awaiting a response from local contacts but in the meantime we do not know if the obstacle is temporary or will become a long-term issue. This post will be updated when we receive more information. The suggested detour is to ride PR 3 between Sparwood and Hosmer.

Attached is a screenshot showing the location of the obstacle.

SR 21 is closed 0.5 mi. E. of Augusta due to a washed out bridge. The workaround is to eliminate the jog NW on US 287 to Augusta, then E on SR 21 back to SR 200 at Simms. This will mean missing the services that are available in Augusta, so be prepared for a stretch of no services between Lincoln and Simms (limited services). SR 200 between US 287 and Simms is very scenic, rolling terrain through the Rocky Mountain Front, but shoulders are variable with some poorly placed rumble strips. Traffic is fast but generally light.
