UPDATE, 6:43 p.m.
All lanes on I-70 were re-opened about 6:15 p.m., following a semi fire near Georgetown, CDOT said. Long delays were still expected.
The Colorado Department of Transportation said it expects at least a six-hour-long closure on eastbound I-70 after a semi crashed and caught fire near Georgetown Saturday afternoon.
The right lane of I-70 east is expected to be closed until at least 8 or 9 p.m., said Lisa Schwantes, a CDOT spokeswoman. The eastbound left lane is still open.
“Right now our cameras are showing that traffic is certainly backed up from Georgetown to about the U.S. 6 exit,” she said.
People headed eastbound toward Denver can exit I-70 at Silverthorne, take State Highway 9 to Fairplay and then take U.S. 285 into Denver, Schwantes said.
