Moffat TunnelEdit profile
The Moffat Tunnel is a railroad and water tunnel that cuts through the Continental Divide in north-central Colorado. Named after Colorado railroad pioneer David Moffat, the tunnel's first railroad traffic passed through in February 1928.
Fifty miles (80 km) west of Denver, Colorado is the East Portal in the Front Range, about 10 miles (16 km) west of the town of Rollinsville, Colorado at 39°54′08″N 105°38′46″W / 39.90235°N 105.6461°W / 39.90235; -105.6461Coordinates: 39°54′08″N 105°38′46″W / 39.90235°N 105.6461°W / 39.90235; -105.6461. The West Portal is near the Winter Park Resort ski area at 39°53′15″N 105°45′41″W / 39.887434°N 105.761347°W / 39.887434; -105.761347. The railroad tunnel is 24 feet (7.3 m) high, 18 feet (5.5 m) wide, and 6.2 miles (10.0 km) long. The apex of the tunnel is at 9,239 feet (2,816 m) above sea level. The Moffat Tunnel finally provided Denver with a western link through the continental divide, as both Cheyenne, Wyoming to the north and Pueblo, Colorado to the south already enjoyed rail access to the West Coast. It follows the right-of-way laid out by Moffat in 1902 while he was seeking a better and shorter route from Denver to Salt Lake City. The water tunnel and the railroad tunnel parallel each other; the water tunnel delivers a portion of Denver's water supply.
The tunnel was the brainchild of David Moffat of the Denver, Northwestern and Pacific (DNW&P) railroad as early as 1902. The original DNW&P tracks climbed Rollins Pass with a series of switch back loops with steep grades and severe snow conditions. Snow removal on the original line made it unprofitable to operate.
Moffat was unable to raise sufficient funds to build the tunnel before he died in 1911, but the forces behind the tunnel continued, and in 1914 a Denver bond issue was approved financing two thirds of the construction cost of the tunnel. The issue was defeated in a court decision which ruled that Denver did not have the constitutional right to enter into a joint venture to construct the tunnel with a private corporation.
In 1920 a bill was introduced in the state legislature to build three tunnels under Monarch Pass, Cumbres Pass, and Rollins Pass (the Moffat Route). The various regions of the state could not come to agreement, partly because southern and southwestern regions feared that Denver would gain a new advantage in commerce from the Moffat Route. Blocking this legislation would ultimately backfire, when Denver was finally able to secure financing for its tunnel.
In early 1922 Denver's lawmakers in the state legislature found an opening. Pueblo had been devastated by a flood, and Gov. Oliver Shoup called an emergency session of the legislature. Denver lawmakers now had power over Pueblo. They would vote for emergency funding for the beleaguered town (an economic rival to Denver) in return for legislation authorizing the issuance of bonds for Denver's tunnel. A deal was struck, and on April 29, the Moffat Tunnel Improvement District was created.
The district boundaries included the City and County of Denver, and all or portions of the counties traversed by the Denver and Salt Lake Railway. The district had the authority to levy taxes and issue bonds backed by real estate within the district. The following summer, bonds were sold and construction began.
The bonds were fully paid off in December 1983, but the commission continued to exist until 1998. It was finally disbanded after a series of political intrigues related to the Winter Park Resort, which was built partly on land owned by the commission (known as the Evans Tract).
In 1988, Rio Grande Industries, the company that controlled the Denver and Rio Grande Western Railroad, purchased the Southern Pacific Railroad. The combined company took the Southern Pacific name because of its name recognition among shippers. On September 11, 1996 Anschutz sold the combined company to the Union Pacific Railroad in response to the earlier merger of the Burlington Northern and the Santa Fe which formed the Burlington Northern and Santa Fe Railway. The Union Pacific Railroad still uses Moffat Tunnel today. Although its primary purpose today is as a rail route for coal and freight and as a water tunnel from the Pacific watershed to the Denver area, tourists and cross-country passengers can enjoy the route on Amtrak's California Zephyr.
The Moffat Tunnel was cut under a shoulder of James Peak. A pioneer tunnel was bored parallel with the main tunnel to facilitate the work and was eight feet high and eight feet wide. In 1925 bad rock at the west end of the tunnel delayed construction and costs soared. The pioneer tunnel was officially 'holed' through on February 18, 1926, the blast of dynamite being set off by President Calvin Coolidge's pressing a key in Washington, and the program was broadcast by radio from the heart of the mountain. The pilot bore later became the water tunnel. Three more bond issues were sold before the tunnel was completed.
Although the original cost of the tunnel was pegged at $6.62 million, final assessments collected by the Moffat Tunnel district, including interest, were $23,972,843. The cost of the two tunnels was $15.6 million, which is $475 per linear foot ($1,558 per linear meter). The project excavated 750,000 cubic yards (570,000 m3), or 3,000,000,000 pounds (1,400,000 t) of rock, equal to 1,600 freight trains of 40 cars each. 28 people died during the five-year project, six in a single cave-in on July 30, 1926.
The tunnel is under lease to the City of Denver, which operates it as a trans-mountain line that transports water to the eastern slope of the range. The railroad tunnel was 'holed' through on July 7, 1927, and formally turned over to the lessee on February 26, 1928. Railroad connections through the tunnel shortened the distance between Denver and the Pacific coast by 176 miles (283 km). The tunnel took 48 months to bore—average daily progress being 21 feet (6.4 m). The first train passed through the tunnel in February 1928.
