Hennepin County has a plan to make it easier for those on foot and bring its sidewalks, traffic signals and curbs into compliance with the Americans with Disabilities Act.

Over the next four years, the county wants to replace or repair pavement and signals that do not comply with the ADA. Residents have until Friday to comment on the Program Access and Transition Plan.

A recent survey of the county's 12,000 pedestrian ramps (curb cuts) found that nearly half need work to comply. It found that a scant 0.25 percent of sidewalks need an upgrade. That can mean moving signs, utility poles or fire hydrants to eliminate barriers to sidewalks.

The changes will cost about $35 million. To comment, e-mail
