Motorists can expect some traffic detours next week as work continues to realign the Louisville and Indiana rail line through Seymour.

Crossings at Second, Third, Fourth, Fifth and Sixth streets will be closed temporarily for rehabilitation work beginning Tuesday.

Schools may experience bus transportation delays because of the project, school officials said.

“We’ll do our best to stay on schedule, but we will have delays at all buildings,” said Tim Fosbrink, director of transportation for Seymour Community School Corp.

Fosbrink said the worst day will be Wednesday, and he expects some bus route delays to be 20 to 30 minutes. He also expects 10- to 15-minute delays Thursday.

All work should be complete and the crossings reopened by Friday, weather permitting, said city engineer Nathan Frey.

Also during this time, the crossing at Seventh Street will be permanently closed. The South Street crossing was permanently closed last month.

When complete, the project will allow trains to move through the city faster, and motorists should notice improved smoothness at the crossings, Frey said.

He doesn’t expect too many problems from the closures.

“I don’t anticipate this situation to be as painful as the U.S. 50 closing,” Frey said.

Because Sixth Street also is State Road 258, a detour will route motorists to Ewing Street (State Road 11), Tipton Street (U.S. 50) and State Road 135.

The schedule for closings is as follows:

Third Street — 9 a.m. Tuesday to 6 p.m. Friday

Fourth Street — 9 a.m. Tuesday to 6 p.m. Thursday

Fifth Street — 9 a.m. Tuesday to 6 p.m. Thursday

Second Street — 6 p.m. Tuesday to 6 p.m. Friday

Sixth Street (State Road 258) — 6 p.m. Tuesday to 6 p.m. Wednesday (24 hours only)
