The new state transportation bill goes into effect Wednesday, but it's unknown when infrastructure improvements will begin in York County.

"Nothing has been confirmed," said Greg Penny, district spokesman for the Pennsylvania Department of Transportation.

Included in the $2.3 billion transportation plan passed by lawmakers in November are several hundred million dollars for local projects.

The biggest chunk will go to a $220 million project to widen Interstate 83 from four lanes to six lanes between the Mount Rose Avenue exit (Exit 18) and the North George Street exit (Exit 22).

"A widening of Interstate 83 is years away because it has to be programmed, and environmental clearances have to be secured," Penny said.

The I-83 project in York County also includes work on 13 bridges throughout North York and Manchester, Spring Garden and Springettsbury townships.

Most of the other work proposed for York County involves multi-million-dollar resurfacing projects.

Specific projects can't be identified publicly until the end of January, Penny said.

Throughout the state, PennDOT is starting with resurfacing and bridge work, spokesman Rich Kirkpatrick said.

The transportation bill will give the state an extra $351 million in 2014 to improve roads, bridges and public transportation. That funding will grow to $2.3 billion by 2018.

"There's not a large influx of funding in the first year. Some work will probably begin in the spring, but it's too early to identify those projects now," Penny said.
