Twenty Route 20 Experiences for the Centennial
The Route 20 designation reaches its centennial in 2026. This page marks that moment by pointing into twenty existing route experiences, from the Pacific endpoint to the Boston finish, rather than treating every road or attraction in the guide as a century old.
Read this as a west-to-east discovery sequence. The numbers are a reading order only, not a ranking or a prescribed travel direction. The centennial belongs to the US Route 20 designation, not to every present-day road, endpoint, alignment, or attraction along the way.
Pacific and western mountain chapters
1 · Oregon
Reach the Pacific endpoint in Newport
Use Newport for a Pacific-endpoint chapter of the current Route 20 story. It is a later endpoint reached through the route's westward growth.
2 · Oregon
Cross Santiam Pass from Sisters toward the Willamette Valley
Use this mountain chapter to connect the central Oregon side of Route 20 with the westward run toward the valley and coast.
3 · Oregon
Drive Oregon's high desert from Vale to Bend
Take this existing trip when a wide-open Oregon chapter is the right scale for your Route 20 plan.
4 · Idaho
Use Boise as the Idaho city reset
Make Boise a larger-city pause within an Idaho sequence that otherwise moves through broad Route 20 country.
5 · Idaho
Cross central Idaho from Arco to Fairfield
Use this interior chapter to follow the existing Arco-to-Fairfield route story without turning it into a separate detour plan.
6 · Montana and Idaho
Re-enter the Route 20 story west of Yellowstone
Start the west-side chapter at the park edge: the US Route 20 designation does not continue through Yellowstone National Park.
7 · Wyoming
Approach Yellowstone through Cody and Wapiti Valley
Use the east-side approach for the final Route 20 chapter before the designation stops at the Yellowstone park boundary.
8 · Wyoming
Cross the Bighorn Basin from Thermopolis to Cody
Use this Wyoming trip to connect the Bighorn Basin chapter with the Cody side of the route.
Plains and heartland chapters
9 · Nebraska
Follow Route 20 across the Nebraska Sandhills
Use the Sandhills segment for a long rural chapter that keeps the route's Nebraska geography in view.
10 · Iowa and Nebraska
Make the Missouri River handoff at Sioux City
Use Sioux City as the planning handoff between the Iowa and Nebraska sides of the Route 20 story.
11 · Iowa
Link Dubuque, Dyersville, and Waterloo
Follow this existing Iowa trip to connect three named stops into one bounded eastern-Iowa chapter.
12 · Iowa
Cross western Iowa from Fort Dodge to Sioux City
Use the existing western-Iowa trip when you want a defined corridor between Fort Dodge and Sioux City.
Great Lakes and Midwest chapters
13 · Illinois
Spend a heritage weekend between Galena and Freeport
Use this Illinois trip for a heritage-focused Route 20 chapter anchored by Galena and Freeport.
14 · Illinois
See where modern US 20 crosses historic Route 66
Use Countryside for the physical-crossing story, where modern US 20 meets the historic Route 66 alignment; it remains the authority for that location.
15 · Indiana
Travel from the Indiana Dunes gateway to South Bend
Use this Indiana trip to connect the Dunes gateway with the South Bend side of the corridor.
16 · Ohio
Explore Ohio's Western Reserve corridor
Use this existing trip to enter the Western Reserve as one connected Route 20 chapter.
17 · Pennsylvania
Follow Pennsylvania's Lake Erie corridor
Use this Pennsylvania trip for a bounded Lake Erie-side chapter of Route 20.
New York and New England finish
18 · New York
Move through the Finger Lakes to Auburn
Use this trip to connect a Finger Lakes chapter with the Auburn side of the route.
19 · Massachusetts
Drive the Berkshires and Jacob's Ladder
Use this Massachusetts trip for a Berkshires and Jacob's Ladder chapter before the eastern finish.
20 · Massachusetts
Reach the eastern endpoint at Kenmore Square
Use the Boston and Kenmore trip for the established eastern-endpoint chapter of Route 20.
Plan from the linked authority
Each card is a handoff, not a replacement for the linked place, trip, segment, or state page. Use those pages and current official sources to check details such as access, closures, weather, hours, and legal stopping conditions before you travel.
Keep the route useful after the anniversary
The centennial is one point in Route 20’s long story. These twenty chapters remain useful after 2026 because they lead back to the guide’s established route-planning authority whenever you are ready to choose a real stretch of road.
