The two sides combine at East Fairview.

ND 200
(it's poorly signed in Montana, Idaho, Washington, and Oregon)
MT 200 (all the way to Missoula? reassurance at Flowing Well, Jordan, Vaughn, Bonner)
(how does it get through Missoula?)
US 12 (MT) (reassurance at Earl Tennant Campground)
US 12 (ID) (reassurance westbound in Lewiston at 21st Street)
US 12 (WA) (also signed along SR 124 - there is at least one sign on US 12 between US 730 and SR 124, so it doesn't split permanently at Waitsburg)
US 395
SR 14
I-5 (may not be signed)
SR 4
SR 401
US 101 (the WSDOT map also shows it using SR 4 to US 101 and going up SR 103, but I can't find any signs)
SR 100 (west side of loop)

US 730 (presumably)
US 30 (all the way? there's at least one reassurance sign eastbound at about I-84 mile 122.2)
(where does it end? Astoria? Fort Clatsop?)

The list above could use some cleanup. I will make a partial attempt below.

Washington
- SR 193

- SR 4
- US 101
- SR 100
- SR 103

The "Lewis and Clark Highway" is defined to follow US 12 through Montana, despite this being nowhere near the actual route L&C took (except west of Missoula). -- NE2 00:40, 24 June 2014 (UTC) reply

Google Street View searches and others claim that it's on parts of Missouri Route 87, Missouri Route 98, Missouri Route 5 and Missouri Route 179. How does it keep jumping over all these places? It's like there's no clear map anywhere in the "Show-Me State." --------- User:DanTD ( talk) 03:13, 30 April 2017 (UTC) reply
