Motorists urged to avoid Silt I-70 interchange
July 28, 2009
SILT, Colo. – Motorists traveling to and from Silt are urged to use alternate routes on either side of Interstate 70, especially during the evening rush hour, while Colorado Department of Transportation crews continue to inspect the overpass bridge at the main Silt interchange that was damaged by a tanker truck Sunday afternoon.
Travel on the overpass bridge is down to a single lane, with alternating travel controlled by a temporary signal.
Use of the restricted bridge during peak travel, mostly westbound I-70 travel into Silt in the evenings, may cause backups on the westbound I-70 off-ramps, CDOT warned.
Motorists can exit I-70 at Rifle or New Castle and use either U.S. 6 for access into Silt, or county roads for access south of Silt.
“This will greatly improve traffic flow on I-70, especially during the evening westbound rush,” according to a CDOT press release.
CDOT closed I-70 at Silt around 12:30 p.m. Sunday after a tanker carrying water hit the overpass bridge. The interstate was reopened by 6:30 p.m., after the accident was cleared and structural engineers had determined the interstate was safe for travel.

Later Sunday evening, the overpass bridge was opened to single-lane, alternating travel.
Monday, CDOT bridge engineers worked with a bridge contractor to further inspect the structure’s steel girders (horizontal support beams), particularly the outside girder on the west side, which took the brunt of the hit by the water tank.
