Rockfall mitigation planned for Glenwood Canyon is expected to cause traffic delays for motorists over the next few months.

Beginning Monday, March 26, the Colorado Department of Transportation will work with Rock Solid Solutions to begin rockfall fence improvements on I-70, east of Glenwood Springs from mile point 122 to 125. 

The $1.5 million project will include the removal of the six existing flex post fences that will be replaced with higher capacity rockfall fences. 

C-DOT says construction of the new rockfall barriers will take place prior to removing the old damaged rockfall barriers. 

While the improvements are underway motorists can expect a westbound right lane closure, east and westbound short-term traffic stops, along with a reduced speed limit of 35 mph. 

The project will be in operation Monday through Thursday from 7 am to 7 pm and is expected to last through August.
