Mesa staffs say Extension Road mill-and-overlay will enable bike lanes; speed limit lowered on one section to 35 mph
Summary
City staff told council that ongoing maintenance paving (mill and overlay) on Extension Road will provide a new surface for bike-lane striping and that one segment’s posted speed will be reduced to 35 mph where a northbound lane is being removed.
City staff on Oct. 2 explained that ongoing road maintenance work on Extension Road — a mill-and-overlay and concrete ramp and curb repairs — sets up the planned bike-lane project and that the posted speed limit on one segment will be reduced from 40 mph to 35 mph.
Public works staff said crews have been repairing ramps and curbs and will begin paving the full section between Baseline and University; once the new surface is in place, crews will restripe the roadway and install delineators and buffered bike lanes per the project approved earlier this year. Staff said tying the bike-lane work to a major maintenance project avoids tearing up new pavement and reduces extra construction time and cost.
The council asked about delineator specifications. Staff said the delineators will be similar to those used on First Avenue but white (rather than green) and spaced roughly 25–30 feet apart, with additional spacing at driveways and openings. The planned configuration includes a buffered bike lane between Baseline and Broadway, a smaller buffer to Main Street and existing conditions north of Main.
Staff also explained that, because the project reduces the northbound direction to a single lane in one section (Baseline to Southern), they recommended reducing the speed limit in that section to 35 mph to match the new lane configuration. No formal action was taken Oct. 2 beyond clarifying construction and striping plans.
