Raised domes alert blind people they’ve reached end of sidewalk Pedestrian walkways in the Fargo-Moorhead metropolitan area are becoming more accessible for people with visual impairments.

Pedestrian walkways in the Fargo-Moorhead metropolitan area are becoming more accessible for people with visual impairments.

As cities make street improvements, they’re required to meet a new Americans with Disabilities Act requirement, said Tom Trowbridge, Moorhead’s assistant city engineer. The improved sidewalks have what are called truncated domes, or raised circles on the pavement that you can feel with your feet to alert blind people they’ve reached the end of the sidewalk.

The domes also are painted a bright color – either yellow or red – so people with slight visual impairments may be able to see the contrast.

“It’s a warning that you’re leaving a safe walk environment and entering a zone where vehicles also travel,” Trowbridge said.

Fargo, West Fargo and Moorhead are adding these improvements while making other repairs, such as the project on Moorhead’s Eighth Street.

“As you do projects, you have to incorporate those changes,” Trowbridge said.

Fargo has been adding the truncated domes in projects for three or four years, said Jeremy Gorden, traffic engineer. Twelfth Avenue North will have the new features when it is completed, he said.
