Great American Rail-Trail Expansion Opens New Ways to Cross the U.S.

New trail segments across several U.S. states are accelerating the build-out of the Great American Rail-Trail, creating fresh opportunities for cross-country cycling, hiking and rail-trail tourism.

A Coast-to-Coast Vision Reaches a New Milestone

The Great American Rail-Trail is envisioned as a more than 3,700-mile, largely traffic-separated route linking Washington, D.C., to Washington State. Publicly available information from Rails-to-Trails Conservancy shows that the project has moved from ambitious concept to on-the-ground reality, with more than half of the planned mileage now open to the public and actively used by walkers, runners and cyclists.

Recent assessments released in 2024 and 2025 indicate that the route is now roughly 55 to 56 percent complete, reflecting steady investments in new trail miles, signage, wayfinding and safety upgrades. Those developments are turning once-fragmented local rail-trails into longer, more continuous corridors that attract both neighborhood users and long-distance travelers.

The route draws on existing rail-trails, canal paths and greenways in 12 states and the District of Columbia, weaving together well-known corridors such as the C&O Canal Towpath, the Ohio & Erie Canalway Towpath Trail and Nebraska’s Cowboy Recreation and Nature Trail. As more gaps close, advocates describe a growing network effect in which each new segment increases the appeal of the trail as a cross-country journey.

Economic studies commissioned in recent years suggest that once fully connected, the Great American Rail-Trail could generate hundreds of millions of dollars annually in new tourism spending, business activity and local tax revenue. Communities along the corridor are already positioning themselves to capture those benefits by improving trailheads, lodging options and bike-friendly amenities.

Midwest States Add Key Miles and Close Gaps

Some of the most visible progress has come in the Midwest, where new investments in Ohio, Indiana, Iowa, Nebraska and Illinois are knitting together existing regional paths into longer-distance routes. Coverage in travel and infrastructure publications notes that in 2025 alone, roughly 18 miles of new Great American Rail-Trail segments came online across these five states and Wyoming, with additional corridors in design or construction.

In Indiana, ongoing work along corridors such as the Pennsy Trail is shortening breaks between established greenways east of Indianapolis. While small in mileage, these projects are critical in transforming disconnected trails into a viable through-route that long-distance riders can follow with minimal on-road detours.

Iowa and Nebraska continue to play a strategic role as the trail crosses the Missouri River and fans west. The Bob Kerrey Pedestrian Bridge between Omaha and Council Bluffs already provides an iconic river crossing, while Nebraska’s long Cowboy Recreation and Nature Trail gives the route a largely off-road backbone across much of the state. New spurs and surface improvements are helping link small towns along this corridor more directly into the cross-country itinerary.

In Illinois, recent attention has focused on significant investments in state park and regional trail infrastructure that intersect with the Great American alignment. Upgrades and extensions on routes such as the Sangamon Valley Trail, completed in 2025, enhance local recreation opportunities while also strengthening Illinois’ role as a central connector between the Great Lakes region and the Plains.

Mountain West and Northwest See Strategic Connections

Beyond the Midwest, expansion in the Mountain West is helping the Great American Rail-Trail feel more continuous between the Great Plains and the Rockies. Reports highlight new mileage in states such as Montana and Wyoming, where a mix of federal grants, state programs and local partnerships is funding trail construction, bridges and grade-separated crossings.

In Montana, planning and engineering initiatives like the Parks to Passes Trail in Powell County are framed as key to closing high-profile gaps in the Great American route. These projects build on a combination of abandoned rail corridors and new multiuse paths to create safer, more direct alignments across mountainous terrain that has traditionally been challenging for long-distance cyclists.

Farther west, Washington State continues to emerge as one of the most advanced sections of the entire route. National travel coverage has pointed to the state’s long-established rail-trails, trestle crossings and tunnel segments as a preview of the immersive experiences the full coast-to-coast trail aims to offer. New wayfinding improvements and surface upgrades are making it easier for visiting riders to string these sections together into multi-day adventures.

Collectively, these Western expansions offer more than scenic value. They also begin to outline a continuous, low-stress travel corridor where travelers can bypass busy highways while connecting small towns, heritage sites and public lands along the way.

Funding, Policy and Local Partnerships Drive Momentum

The pace of expansion is closely tied to funding decisions at multiple levels of government. Publicly available records show that recent years have brought an influx of support from federal competitive grant programs, state active-transportation funds and local capital budgets. Some states have updated their transportation alternatives programs specifically to prioritize large-scale trail networks and long-distance corridors like the Great American Rail-Trail.

National nonprofits, regional trail alliances and municipal governments are frequently cited as collaborators in planning and permitting new segments. Their efforts range from securing right-of-way access on former rail lines to negotiating road crossings, environmental reviews and community design elements such as lighting, art and trailhead facilities.

Private philanthropy and tourism-driven investment are also playing a role. Hospitality businesses, outdoor recreation companies and local chambers of commerce increasingly view the trail as infrastructure that can attract visitors in shoulder seasons, support cycling events and encourage repeat travel. This diversified funding base has helped keep projects moving even as construction costs and permitting timelines vary from state to state.

According to recent route assessments, more than 100 miles of new trail have been added to the Great American alignment since the official cross-country route was announced in 2019. That figure reflects not only raw mileage, but also the growing number of communities that have formally integrated the trail into their economic development, climate, and transportation plans.

New Travel Itineraries Emerge Along the Expanding Route

As segments multiply and gaps narrow, travelers are beginning to treat the Great American Rail-Trail as more than a long-term vision. Guidebook authors, specialty tour operators and cycling media outlets now feature it as a viable basis for weeklong trips, state-to-state rides and themed journeys focused on history, food or landscapes.

In practice, most visitors are not yet riding the entire cross-country route. Instead, they are combining well-developed stretches, such as the towpaths and rail-trails between Washington, D.C., and Pittsburgh or the long gravel corridors in Washington State, with shorter connector rides and public transit links. This mix-and-match approach allows travelers to experience the character of the developing trail while infrastructure catches up in remaining gaps.

Communities along the corridor are responding with new services tailored to trail users. Bike-friendly lodging, shuttle services, baggage transfers and local tour packages are becoming more common near high-traffic segments, making it easier for less-experienced riders and families to attempt multi-day trips. Seasonal events and festivals are increasingly marketed around nearby trail access, bringing additional visibility to smaller destinations.

With more new mileage planned in the coming years, the Great American Rail-Trail is poised to further change how people think about traversing the United States. For domestic and international travelers alike, the expanding network offers the prospect of seeing the country at human speed, one connected rail-trail segment at a time.
