- Eisenhower Tunnel
.
The tunnel is a two-bore tunnel with each bore approximately 1.7 miles (2.7 km) long. Construction of the westbound bore was started on
March 15 ,1968 and finished onMarch 8 ,1973 . The eastbound bore was started onAugust 18 ,1975 and completed onDecember 21 ,1979 . From1973 -79 the westbound bore carried a single lane of traffic in each direction. The total construction cost of the project was $108 million. In2002 , over ten million vehicles passed through the tunnel, many of them driving between the Denver area and popularskiing locations west of theContinental Divide . The eastern end of the tunnel is under and surrounded by theLoveland ski area .Truck s that cannot safely pass through the tunnel (trucks over 13' 6" (4.1m) in height and trucks carryinghazardous materials ), andbicycle s andpedestrian s, must take the long and steep climb and descent of US 6 acrossLoveland Pass .Tourist s who want to take aphotograph from the scenery at anelevation of 11,990 feet (3655 m)above mean sea level must also take Loveland Pass. Aside from that, the tunnel has replaced the pass. Despite being much less formidable than the old route, the approach to the tunnel on both sides is steep (up to 7% in places), and runaway truck ramps are available for truckers who lose control. The tunnel's ascent/descent can also be dangerous in winter.ee also
