The Johns Creek City Council has awarded a $399,485 construction contract to R.J. Haynie & Associates Inc. to replace a pair of span-wire traffic signals with mast-arm signals.

Old Alabama road at Preston Oaks Drive/Breckenridge Close, and Jones Bridge at Taylor roads, will get new signals, Public Works Director Lynette Baker said in a council agenda report. Haynie submitted the lowest of three bids for the work.

During an annual inspection in 2016, Johns Creek staff noted 10 traffic signals on timber poles, and signal heads beginning to sag below clearance standards, creating a safety issue, Baker said. The city adopted a long-term strategy to replace these signals.

“The project converts the two existing signals from wooden poles with span wire to mast arms, which eliminates the safety concern” — leaning wooden poles and signal heads sagging — “and creates a durable, aesthetically pleasing replacement with capability to hold video and traffic detection equipment,” Baker said.

Haynie will have 180 days to complete the project.
