Big bump work narrows I-70 for rest of summer
July 15, 2012
Colorado Department of Transportation crews set up shop for several more months of work on Interstate 70’s “big bump” a mile west of the Eisenhower Tunnel.
The work is expected to continue to take up one lane in each direction through October, CDOT officials said.
“The work has really jumped into high gear … now that the holiday is over,” CDOT spokesman Bob Wilson said. “It will remain in that (two-lane) configuration even through Labor Day so we can get it completed, and we hope to get it done by the end of October so we can beat the snow.”
One lane will be closed on both the east- and westbound directions of the interstate, although which lane is closed will change. Currently, the far left lanes are closed to allow crews to work in the center median area.
The speed limit has been lowered to 50 mph through the work zone.
The $2.5 million project is intended to stop a bump from rising in the eastbound lanes of the highway. Landslide movement under the interstate has caused the disturbance in the road to reappear even after crews pave over it.
The current project is expected to be a long-term fix for the issue. A similar solution was implemented on the westbound lanes of the highway in 2010 and has been fairly successful so far.
CDOT also is doing grout work on the eastbound bore of the Eisenhower Tunnel, causing single-lane closures at night. The closures are not expected to cause significant traffic impacts.
