Interstate 70 swings northeast to circumvent Douglas Mountain from Empire Pass east to U.S. 40. Photo taken 08/11/16.
Increasing traffic, especially on weekends, led to the implementation of the I-70 Mountain Express Lane. The toll lane starts at the trumpet interchange (Exit 232) with U.S. 40 east. Photo taken 08/11/16.
The Mountain Express Lane utilizes all electronic tolling (AET). Collection methods use ExpressToll transponders or toll by plate at a higher rate. Photo taken 08/11/16.

U.S. 40 is the primary route west from Denver and I-70 to Salt Lake City. U.S. 40 is an all-weather highway, but care should be taken when traversing the highest points in winter, such as Rabbit Ears Pass near Steamboat Springs. Photo taken 08/11/16.
West from Exit 232, U.S. 40 follows the West Fork of Clear Creek to Stanley Mountain, where it turns north through a series of switchbacks to Berthoud Pass. The US highway reaches Winter Park ski area in 25 miles. Ski Granby Ranch lies 20 miles further. Photo taken 08/11/16.
U.S. 40 is the best route from Interstate 70 into Rocky Mountain National Park during the summer months, as the trip requires only a brief journey east on U.S. 34. However, Estes Park (at the eastern entrance to the park) is not accessible via this route during the winter.

The I-70 Mountain Express Lane was implemented by the Colorado Department of Transportation to reduce congestion between Empire and Idaho Springs. The $72 million project converted the eastbound shoulder into a travel lane for use during peak periods. Variable tolling increases costs during heavier traffic to ensure acceptable travel speeds.1 Photo taken 08/11/16.
The Express Lane acts as a breakdown lane during non peak periods. Lane changes are only permitted at ingress and egress points. Photo taken 08/11/16.
Although signed exclusively for the port of entry (weigh station), Exit 234 also connects with old U.S. 6-40 (Frontage Road) and several travelers services. Photo taken 08/11/16.
Old U.S. 6-40 runs along the north side of I-70 from Downieville at Exit 234 to a half diamond interchange (Exit 235 on I-70 west) in nearby Dumont. Photo taken 08/11/16.

A Colorado scenic byway, Colorado 103 meanders west and south to Echo Lake, where it connects with Colorado 5. Leading to the summit of Mount Evans (el. 14,264 feet), Colorado 5 is the highest state highway in the country. Photo taken 08/11/16.
SH 103 climbs onto Warrior, Chief and Squaw Mountains east from SH 5 to end at County Road 151 (Little Bear Creek Road). Little Bear Creek Road north ties into Soda Creek Road south of Idaho Springs. Photo taken 08/11/16.
Continuing east over Clear Creek and Soda Creek Road, another set of dynamic message and speed limit signs appear. Photo taken 08/11/16.

A chain station lines the south side of Interstate 70 at milepost 242. The freeway remains within the Idaho Springs city limits east to Exit 243. Photo taken 08/11/16.
Previously upcoming Exit 243 consisted of a diamond interchange serving local traffic for the south side frontage road at Hidden Valley. The introduction of gambling in the early 1990s at Black Hawk and Central City propelled growth in both of the small cities. With increasing traffic along SH 119 from U.S. 6 to the southeast, Central City government and area businesses funded a $38 million project to build a new highway providing a direct route with Interstate 70. Named Central City Parkway, the winding corridor opened north from Exit 243 on November 19, 2004.1 Photo taken 08/11/16.
The Mountain Express Lane extends east through the Idaho Springs Twin Tunnels. Construction in 2013 expanded the eastbound tunnel by an additional lane. This work followed a 2012 project to add a modern frontage road along the south side of I-70 from nearby to Exit 243. During a prolonged detour, eastbound motorists were redirected onto the adjacent service road as crews widened the tunnel.4 Photo taken 08/11/16.
The $55 million Twin Tunnels project commenced along I-70 east in April 2013. Work also included expansion of the westbound bore to include space for a future westbound lane. That tunnel closed to traffic in April 2014 and reopened in December 2014.5 Photo taken 08/11/16.
