The Snoqualmie Tunnel is a former railroad tunnel near Snoqualmie Pass in the U.S. state of Washington , located east of Seattle . The tunnel crosses the Cascade Range about three miles ( 5 km ) south of pass , which is used by Interstate 90 , on the border between King County and Kittitas County . It is 11,894 feet ( 2.253 mi ; 3.625 km ) long and is at an approximate elevation of 2,600 feet ( 790 m ) above sea level , just north of Keechelus Lake . Its east portal is at Hyak . The tunnel was originally constructed for the Chicago , Milwaukee , St. Paul and Pacific Railroad in the early 1910s and was abandoned in 1980 . It now serves as part of a rail trail in Iron Horse State Park , known officially as the Palouse to Cascades State Park Trail . The trail was formerly known as the John Wayne Pioneer Trail or the commonly called the Iron Horse Trail . A major renovation to the walls , ceiling , and path were completed in July 2011 after a two-year closure .
The Palouse to Cascades State Park Trail , formerly known as the John Wayne Pioneer Trail , is a rail trail that spans most of the U.S. state of Washington . It follows the former railway roadbed of the Chicago , Milwaukee , St. Paul & Pacific Railroad ( Milwaukee Road ) for 300 miles ( 480 km ) across two-thirds of the state , from the western slopes of the Cascade Mountains to the Idaho border . The former Milwaukee Road roadbed was acquired by the state of Washington via a quitclaim deed , and is used as a non-motorized recreational trail managed by the Washington State Parks and Recreation Commission and by the Washington State Department of Natural Resources . State legislation railbanked the corridor with provisions that allow for the reversion to railroad usage in the future . The trail was originally named the John Wayne Pioneer Trail in honor of the John Wayne Pioneer Wagons and Riders Association for their assistance in creating the trail . The 100-mile ( 160 km ) portion from Cedar Falls ( near North Bend ) to the Columbia River south of Vantage has been developed and is managed as the Iron Horse State Park . In 2002 , it was designated a National Recreation Trail . In 2018 , the trail was renamed to the Palouse to Cascades State Park Trail by the Washington State Parks and Recreation Commission .
The St. Paul Pass Tunnel was a railway tunnel in the northwest United States at St. Paul Pass , on the Montana-Idaho border . The tunnel was on the main line of the Chicago , Milwaukee , St. Paul & Pacific Railroad , commonly known as The Milwaukee Road . The pass is on the Bitterroot Range of northwestern Montana and the Idaho Panhandle . The Milwaukee Road crossed under it in the St. Paul Pass Tunnel , also known as the Taft Tunnel , completed in 1908 ; its length is 8,771 feet ( 1.66 mi ; 2.67 km ) at 4,150 feet ( 1,265 m ) above sea level at East Portal in Montana . The pass above the tunnel is at an elevation of 5,162 feet ( 1,573 m ) . The East Portal is two miles ( 3 km ) southwest of exit 5 of Interstate 90 . With ongoing financial problems which worsened in the 1970s , the Milwaukee line abandoned its right-of-way in the West in 1980 , but the tunnel and its approach grades have been revived as a rail trail route for hikers and bicyclists , the Route of the Hiawatha Trail .
Lookout Pass Ski and Recreation Area is a ski area in the western United States . It is at Lookout Pass on Interstate 90 , on the border of Idaho and Montana , five miles ( 8 km ) east of Mullan , Idaho . It has a summit elevation of 5,650 ft ( 1,720 m ) on Runt Mountain with a vertical drop of 1,150 ft ( 350 m ) on the northeast-facing slopes . Lookout Pass operates five days per week ( closed Tuesday & Wednesday ) during the ski season , and daily during the Christmas vacation break . The area has tripled in size since 2003 ; new terrain was opened to the southeast-facing slopes on the Montana side of the border in December 2003 , and on the northwest-facing North Side ( in Idaho ) in 2006 . There are three double chairlifts and one triple chairlift at Lookout Pass , whose average annual snowfall exceeds 350 inches ( 890 cm ) . The elevation of the highway pass on I-90 is a moderate 4,720 feet ( 1,440 m ) . The historic Mullan Pass , constructed as a wagon road by the U.S. Army in 1860 , is about three miles ( 5 km ) east-northeast as the crow flies , at 5,168 feet ( 1,575 m ) . Lookout Pass is considered the eastern boundary of Idaho 's Silver Valley mining region . Opened 85 years ago in 1935 , the Lookout Pass ski area operates under a special-use permit of the U.S. Forest Service , in the Idaho Panhandle National Forests ( formerly the Coeur d'Alene National Forest ) . Gradual enhancement of the area has occurred over the decades , and the first chairlift was installed in the summer of 1982 . The community ski hill , run by the nonprofit Idaho Ski Club , was sold in 1992 to Lookout Recreation , Inc. , a company formed by two 27-year-old former college roommates , Don Walde of Wallace and Jim Fowler .
Sideling Hill Tunnel is one of three original Pennsylvania Turnpike tunnels abandoned ( this one in 1968 ) after two massive realignment projects . The others are nearby Rays Hill Tunnel , and farther west , the Laurel Hill Tunnel . It was less expensive to realign the Turnpike than to bore a second tube for four lane traffic . Sideling Hill Tunnel is 6,782 feet ( 2,067 m ) long . It was the longest of the original tunnels on the Pennsylvania Turnpike . The Ray 's Hill Tunnel and Sideling Hill Tunnel are now part of the Pike2Bike Trail . Together , the two tunnels as well as the roadway are commonly known as the Abandoned Pennsylvania Turnpike . From the Turnpike 's opening in 1940 until the realignment projects , the tunnels were bottlenecks ; opposing traffic in the same tubes reduced speeds . Four other tunnels on the Turnpike - Allegheny Mountain , Tuscarora Mountain , Kittatinny Mountain , and Blue Mountain - each had a second tube bored , the least expensive option . All of the original tunnels except for the Allegheny Mountain Tunnel were part of Vanderbilt 's Folly , the never-completed South Pennsylvania Railroad .
The Abandoned Pennsylvania Turnpike is the common name of a 13-mile ( 21 km ) stretch of the Pennsylvania Turnpike that was bypassed in 1968 when a modern stretch opened to ease traffic congestion in the tunnels . In this case , the Sideling Hill Tunnel and Rays Hill Tunnel were bypassed , as was one of the Turnpike 's travel plazas . The bypass is located just east of the heavily congested Breezewood interchange for Interstate 70 ( I-70 ) eastbound at what is now I-76 exit 161 .
Combe Down Tunnel is on the now-closed Somerset and Dorset Joint Railway main line , between Midford and Bath Green Park railway station , below high ground and the southern suburbs of Bath , England , emerging below the southern slopes of Combe Down village . Opened in 1874 , this 1,829-yard ( 1,672 m ) long disused railway tunnel was once the UKs longest without intermediate ventilation . The tunnel now forms part of the £1.8 million Two Tunnels Greenway walking and cycling path opened on 6 April 2013 and is the longest cycling tunnel in Britain . Its custodian is Wessex Water .
The Two Tunnels Greenway is a shared use path for walking and cycling in Bath , Somerset , England . The route is National Cycle Route 244 . The route joins National Cycle Route 24 south of Bath , with National Cycle Route 4 which runs through Bath .
Ausserberg is a municipality in the district of Raron in the canton of Valais in Switzerland .
The canton of Valais ( UK : /ˈvæleɪ/ VAL-ay , US : /væˈleɪ/ val-AY , French : [ valɛ ] ( listen ) ; German : ( Kanton ) Wallis [ ˈvalɪs ] ( listen ) ; Italian : ( Canton ) Vallese [ valˈleːze , -eːse ] ) is one of the 26 cantons of Switzerland , situated in the southwestern part of the country , around the valley of the Rhône from its headwaters to Lake Geneva , separating the Pennine Alps from the Bernese Alps . The canton is simultaneously one of the driest regions of Switzerland in its central Rhône valley and among the wettest , having large amounts of snow and rain up on the highest peaks found in Switzerland . The canton of Valais is widely known for the Matterhorn and resort towns such as Crans-Montana , Saas Fee , Verbier and Zermatt . It is composed of 13 districts ( hence the 13 stars on the flag ) and its capital is Sion .
Switzerland , officially the Swiss Confederation , is a country situated in the confluence of western , central , and southern Europe . [ note 4 ] It is a federal republic composed of 26 cantons , with federal authorities seated in Bern . [ note 1 ] Switzerland is a landlocked country bordered by Italy to the south , France to the west , Germany to the north , and Austria and Liechtenstein to the east . It is geographically divided among the Swiss Plateau , the Alps , and the Jura , spanning a total area of 41,285 km2 ( 15,940 sq mi ) , and land area of 39,997 km2 ( 15,443 sq mi ) . While the Alps occupy the greater part of the territory , the Swiss population of approximately 8.5 million is concentrated mostly on the plateau , where the largest cities are located , among them the two global cities and economic centres of Zürich and Geneva . The establishment of the Old Swiss Confederacy dates to the late medieval period , resulting from a series of military successes against Austria and Burgundy . Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648 . The Federal Charter of 1291 is considered the founding document of Switzerland which is celebrated on Swiss National Day . Since the Reformation of the 16th century , Switzerland has maintained a strong policy of armed neutrality ; it has not fought an international war since 1815 and did not join the United Nations until 2002 . Nevertheless , it pursues an active foreign policy and is frequently involved in peace-building processes around the world . Switzerland is the birthplace of the Red Cross , one of the world 's oldest and best known humanitarian organisations , and is home to numerous international organisations , including the second largest UN office . It is a founding member of the European Free Trade Association , but notably not part of the European Union , the European Economic Area or the Eurozone .

The trail takes around three days to complete for most fitness levels . It is one of the easiest cycle trails in New Zealand and offers a diverse range of scenery , from pohutukawa trees , through lush farm land , and onto some of New Zealand 's pioneering past .
Rays Hill Tunnel is one of three original Pennsylvania Turnpike tunnels which were abandoned ( this one in 1968 ) after two massive realignment projects . The others included the Sideling Hill Tunnel , and farther west , the Laurel Hill Tunnel . Rays Hill Tunnel is 3,532 feet ( 1,077 m ) long . It was the shortest of the seven original tunnels on Pennsylvania Turnpike . Due to its short length , it only contains ventilation fans at its western portal . Its eastern portal is the only one of the 14 tunnel portals on the original turnpike that has no ventilation fan housing . It can be seen by westbound traffic on the Turnpike . The tunnel connects Bedford and Fulton Counties in South Central Pennsylvania .
The Erie to Pittsburgh Trail is a rail trail currently [ when ? ] in development in Western Pennsylvania and Western New York . When completed the trail will stretch approximately 270 miles from Erie , Pennsylvania , to Pittsburgh , Pennsylvania . It will connect to the Great Allegheny Passage and the C & O Canal to create 605 miles of continuous off-road trail from Erie , Pennsylvania , to Washington , D.C . It will also connect to the Erie Canal trail via the flat New York Bike Route 517 along Lake Erie . The trail features two old railroad tunnels : the 2868-foot-long ( 874 m ) Rockland Tunnel and the 3350-foot-long ( 1021 m ) Kennerdell Tunnel . The Kennerdell Tunnel is one of the longest rail-to-trail converted tunnels in the United States , and the 10th longest bicycle/pedestrian tunnel in the world .
The Big Savage Tunnel is a formerly abandoned railway tunnel located about 9 miles ( 14 km ) southeast of Meyersdale , Pennsylvania .

The Great Allegheny Passage ( GAP ) is a rail trail system in Maryland and Pennsylvania - the central trail of a network of long-distance hiker-biker trails throughout the Allegheny region of the Appalachian Mountains , connecting Washington , D.C. to Pittsburgh , Pennsylvania . It consists of several smaller trails including the Allegheny Highlands Trail of Maryland , the Allegheny Highlands Trail of Pennsylvania and the Youghiogheny River Trail . The GAP 's first 9-mile ( 14 km ) section near Ohiopyle , Pennsylvania , opened in 1986 . The 9-mile ( 14 km ) section between Woodcock Hollow and Cumberland opened on December 13 , 2006 . In June 2013 , thirty-five years after construction first began , the final GAP section was completed ( from West Homestead to Pittsburgh ) at an overall cost of $ 80 million and gave Pennsylvania the most open trail miles in the nation ( 900 miles , with 1,110 miles under development ) . The completion project was titled The Point Made , because it was now possible to reach Point State Park in Pittsburgh from Washington , D.C. Celebrations took place on June 15 , 2013 . The multi-use trail , suitable for biking and walking , uses defunct corridors of the Baltimore and Ohio Railroad , Pittsburgh and Lake Erie Railroad , Union Railroad and the Western Maryland Railway - extending 150 miles ( 240 km ) from Cumberland , Maryland to Point State Park in downtown Pittsburgh , and includes the 52-mile ( 84 km ) branch ( Montour Trail ) to the Pittsburgh International Airport . Completing a continuous , non-motorized corridor from Point State Park 335 miles ( 539 km ) to Washington , D.C. , the GAP connects with the Chesapeake and Ohio Canal towpath trail , which runs 184.5 miles ( 296.9 km ) between Cumberland and Washington , D.C . The Allegheny Trail Alliance ( ATA ) - a coalition of seven trail organizations related to the GAP ( Friends of the Riverfront , Steel Valley Trail , Regional Trail Corporation , Ohiopyle State Park , and Mountains Maryland ) maintains the 150-mile GAP , which is also a segment of the Potomac Heritage National Scenic Trail , one of eight nationally designated scenic trails . The trail 's formal name , the Great Allegheny Passage , was selected in 2001 by the ATA after six years and more than 100 proposals as a name evocative of the geography and historical heritage of the trail , having been suggested by Bill Metzger , editor of the ATA newsletter . The trail used a temporary name , the Cumberland and Pittsburgh Trail , before its official name was adopted . The second runner-up title for the trail was the Allegheny Frontier Trail .
