SUMMERVILLE -- Right at scenic Hutchinson Square in the heart of this town -- boom, the car gets a jolt.

It's the "speed bump" at the Norfolk-Southern railroad crossing on Main Street, where the road rises to rattle motorists across gouged-out timber ties, exposed spikes and track. The town has gotten complaints, the rail company has gotten complaints, and on Thursday a railroad crew will be out trying to fix it.

That will cause a little rattle of its own. Main Street, which is the busy U.S.17A throughway, is scheduled to be closed 8:30 a.m.-4 p.m.

"We scheduled it intentionally after (morning) rush hour is over, and hope to get it done before evening rush hour," said Summerville Police Sgt. Richard Peeples.

Traffic will be detoured to Cedar Street at Richardson Avenue coming from the south and West First North Street coming from the north. Four Summerville Police officers will be assigned to handle traffic back-ups. Motorists are urged to divert on their own to the Berlin Myers Parkway or another route around town.
