🚜WHAT? Beginning early April, crews will replace deteriorated concrete panels and aging asphalt, complete bridge rehabilitation work and install new concrete overlay near Seibert. Other improvements will include guardrail replacement, new delineators, updated roadway signage and fresh pavement striping.
On CO 57 near Stratton, the roadway will be milled and paved, with additional curb and gutter work, new signage installation and pavement striping.
