Pay attention and prepare to be aggravated.
That's the best advice for drivers on Interstate 83 between Mount Rose Avenue and George Street during rush hours.
Long lines of cars trying to exit appear suddenly, often spilling from exit lanes into travel lanes.
The lucky drivers must merge quickly to the left; the unlucky ones have to settle in for a long, frustrating wait for their turns to exit.
Not only is it an unsafe waste of time and fuel, it's also bad for business.
The York County Economic Alliance has been calling for improvements for years, saying the state of our infrastructure makes it inefficient for companies to transport their goods.
That's to say nothing of new businesses that might have considered a move to York County ... until they got a look at our roads and bridges.
Fortunately, either of two competing transportation funding bills under consideration in the state Legislature would help provide much-needed relief.
Both Gov. Tom Corbett's $1.8 billion transportation plan and the state Senate's recently approved $2.5 billion version earmark several hundred million for projects in York County.
Those include 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), as well as work on 13 bridges throughout North York and Manchester, Spring Garden and Springettsbury townships.
The bills also pave the way for several multimillion-dollar resurfacing projects in York County.
Good news, indeed -- not only for the safety and efficiency improvements, but also for the jobs the projects will create. Both were reasons state Sen. Rob Teplitz supported the Senate bill.
The Dauphin County Democrat, who also represents part of York County, was the source of the information about the local benefits of the bills, citing a state Department of Transportation database that hasn't been made public.
Transportation Secretary Barry Schoch said that's because the current list of projects is tentative and won't be finalized until his department knows exactly how much it has to work with.
The good news is both the governor's and Senate bills include the York County work. So even if the House version ends up somewhere in the middle, as is expected, it looks good for local motorists.
Until the governor signs the legislation, though, we'll all just have to white-knuckle it a little longer.
