relocating the S.H. 119 and U.S. Highway 6 intersection to 1-
70 at the Floyd Hill interchange (located at the top of Floyd
Hill), and
constructing a new roadway to connect with S.H. 119 in North
Clear Creek Canyon to the Floyd Hill interchange at 1-70.
Highway relocation within Clear Creek Canyon (Alternatives 1, 2, and
3) would have a construction cost estimated to be in excess of $230
million. Highway relocation outside of Clear Creek Canyon
(Alternatives 4, 5, and 6) would have a construction cost estimated
to range from $84 million to $112 million.
User costs for value of time and vehicle operating cost are expected
to increase for all of the U.S. Highway 6 relocation alternatives.
User costs for accidents are estimated to decrease for all of the
roadway relocation alternatives due to improved roadway design
standards. The net result of user cost analysis shows the highway
relocation alternatives 1, 2 and 3 are expected to reduce annual
user costs from $0.5 million to $1.9 million annually. Alternatives
4, 5 and 6 are estimated to increase user costs from $1.7 million
to $2.1 million.
Preliminary evaluations indicate the six roadway relocation
alternatives should increase safety for traffic currently using U.S.
Highway 6.
For highway relocation within the canyon, travel times between Idaho
Spri ngs and Golden are expected to increase by 1 to 3 mi nutes.
Travel times between Black Hawk and Denver or Golden are predicted
to change by less than 1 minute. For highway relocation to 1-70,
travel time between Denver and mountain locations would be reduced
4 to 5 minutes. A 6 to 8 minute increase would be expected between
Golden and mountain locations.
