route.
The ridges between Elroy and Sparta were tunneled at great expense and with much difficulty. The Baraboo Air Line was consolidated with the C&NW in 1872.
The Baraboo Air-Line Rail Road connected to the LaCrosse, Trempeleau & Prescott Railroad at
Winona Junction and opened for traffic in September 1873, through to Winona, Minnesota. In 1874, the C&NW reported an expenditure for its three tunnels of $476,743.32 and for the construction of 129 miles of railroad between Madison and Winona Junction of $5,342,169.96.
By 1911, the Chicago and North Western completed a new route from Adams to Sparta through Wyeville, called the Adams Cutoff, which avoided the steep grades of the Elroy to Sparta cutoff.
In 1964 the Chicago and North Western was permitted to abandon the stretch from Elroy to Sparta.
The Wisconsin Conservation Commission, the forerunner of the Wisconsin Department of Natural Resources, purchased the trail property for $12,000.
The trail came into use in 1967. The commission learned that 40% of the users were bicyclists, who required a smoother road.
The trail was surfaced with screened limestone, and the bridges received planking by 1970.
The trail was made part of the National Trails system in 1971.

for a smooth ride for bicyclists. The three tunnels along the trail are impressive feats of nineteenth-century railroad engineering. Tunnel 1, a short distance from Kendall, is surrounded by natural tunnels formed by the surrounding canopy of trees. Tunnel 2, located halfway between
Wilton and
Norwalk, features wooden doors on both ends of the tunnel. Both Tunnels 1 and 2 are a each. Tunnel 3, from Sparta and from Norwalk, is longer than the length of ten football fields at .
Seasonal closing
The tunnels are closed for the season by the beginning of November, using the doors that the railroad added to prevent storm damage. The debate on when to close the tunnel caused a conflict between the U.S. Fish and Wildlife Service and the organizers of the Rails to Trails Marathon. The
northern long-eared bat hibernates in Tunnel Number three. It was listed as threatened species in 2015. The Rails to Trails Marathon, a Boston Marathon qualifier, moved their event date to earlier in October from November in 2017 to accommodate an earlier tunnel closing than the original November 15 date.
Location
The eastern end of the trail is on just north of in downtown Elroy (), while the western end is at the intersection with the La Crosse River Trail on John St. in Sparta (). The trail headquarters, located in
Kendall on
Wisconsin Highway 71, is open from May 1 through October 31. There is a fee for use of the trail if one does not have an annual Wisconsin trail pass. Camping, lodging, food, parking, bike rentals and information are available at many points along the trail.
