DAUPHIN, Pa. (WHTM) – Update: The installation of the second contra-flow gate was completed Saturday.

PennDOT said traffic was restored to two lanes in both directions around 10 p.m.


Previously Reported:

Heads up — a major Midstate highway will probably see delays this weekend.

A construction project that aims to (eventually) make traffic flow better will slow things down temporarily.

Look for one lane open each way: The left lane eastbound and westbound on Route 22/322 will be closed through Dauphin Borough from Friday night through the weekend.

That, of course, means traffic.

“I don’t think we expect it to be too bad,” said PennDOT spokesman Greg Penny. The agency is installing what’s called a contra-flow gate near Route 443.

“This is an area that when we have a crash, we don’t really have an alternative, especially in the eastbound direction,” Penny said.

This will change that. The agency already installed one near Route 225 on the other side of Dauphin Borough.

It’s a metal barrier, similar to a guardrail, in the concrete median.

When both gates swing open into the left lanes of each direction, it’ll allow PennDOT to push traffic from one side to the other — creating one lane in each direction, but on one side of the divided highway — to keep things flowing.

“We’re gearing up for the project when we close Route 11/15 down for three months,” Penny said. Route 22/322 will be the main detour during the Marysville Rock Slope Project, which will close Route 11/15 starting at the beginning of May.

PennDOT created a new section of their 511 PA website to help drivers navigate that detour; you can see travel times for the entire route, but the lane restriction this weekend is just a small portion of that — from Route 433 to Route 225.

Usually, that section takes about two minutes.

“A good time to check [the website] will be this Saturday to see how well it’s running,” Penny said.

The lanes are scheduled to reopen by 6 a.m. Monday, if not sooner.
