|Square grid manhole cover|
This manhole cover sports a simple square grid pattern which adds texture and reduces the risk of slipping when wet.
|Diamond grid electric access cover|
This manhole cover indicates that it provides access to the electric cabling that is below ground. The oval identifier is a nice contrast to the diamond grid pattern. The cracks in the sidewalk look like electric arcs that have been frozen in the sidewalk.
|Eight holed sewer cover|
The eight ventilation holes and the ribbing combine to create a simple pattern.
|Gas box cover|
The raised "B & T" and "GAS" lettering and ribbing get rubbed and buffed by tires. "B&T" stands for Bingham & Taylor, who have been in the business since 1849.
