On the advice of the township traffic engineer, Upper Macungie supervisors voted to close certain stretches of four roads to tractor trailers.
At the township's request, Scott Stenroos of Keystone Consulting Engineers studied four sections of roads and deemed them too curvy and narrow for tractor trailers.
The roads are:
-- Oldt Road between Adams Road and Wood Lane
-- Wood Lane between Adams Road and the township line
-- Arrowhead Lane between Schantz Road and Wood Lane
-- Weiss Road between Ziegels Church Road and Wood Lane
Some residents of those areas had complained about the truck traffic, Stenroos said. He surmised that tractor trailers might be coming out of Lehigh Valley West Industrial Park and taking the back roads in an effort to find their way to Route 863.
"The roads are very narrow and the curves are very sharp," Stenroos said.
The supervisors voted unanimously to prohibit tractor trailers on those roads. Stenroos said he expects the stretches to be posted in 30 to 60 days.
