A project dubbed by the Colorado Department of Transportation as the “Big Bump” closes lanes along I-70 about one mile west of the Eisenhower Tunnel.
The $2.2 million project will force those lanes closed through October.
Over the years as CDOT has tried to smooth out this natural depression 6-feet of asphalt has built up in that section.
CDOT Engineer Peter Kozinski explains, “We’re attempting to mitigate the Big Bump by drilling 5-foot diameter holes, about 20-feet deep and then filling them with a lightweight concrete material.”
In August, the project will include some rockfall mitigation work about four miles west of the Big Bump. Crews will install draped mesh and barrier along WB I-70. There will be lane closure there as well when that portion of the project gets under way.
