A diverging diamond interchange now connects Route 19 and I-70 in South Strabane Township, Washington County. Pennsylvania Gov. Tom Wolf and other state and local officials gathered for a ceremonial ribbon cutting to mark the completion of the $63 million replacement for the old cloverleaf interchange. The new design is intended to reduce crashes but it may catch you by surprise because it moves you over to the left-side road when you approach the interchange.There are big traffic islands painted red, a curb, and a jersey barrier to protect and guide you. Alternating traffic lights bring drivers in the opposing lane to a full stop before the lanes cross over, and there are direction signs and lane markings. Its diverging diamond design at the location is a first for Pennsylvania but in other parts of the country, the design has reduced the number of crashes."I think it's very good. And it's really nice. It was kind of confusing at first, when they first opened it up," said Frank Gordon of Washington, Pennsylvania. "I think people are safe driving it. I feel really safe driving it. As a matter of fact, it's way better than it was before they did it.""At first it did (confuse me) because you think you're on the wrong side of the road when you're going to the left, but now, it's fine," said Janie Gilbert of Claysville. "I think it's fine. It makes the traffic flow quicker and there's not such a bottleneck right back there like there used to be. So i think it's good."Not everyone is happy with this new pattern."Like when my aunt recently came to visit, she thought she was driving on the wrong side of the road and had no clue what was going on. So, to me, it's a mess," said Corey Gibbon of Washington, Pennsylvania. "People trying to get over into lanes, they don't know where they're going . Everybody's confused . It may make it a little bit easier to get onto the highway."The traffic patterns of the diverging diamond interchange have been in place since last September, but final work on the project was recently completed. There used to be a couple of dozen vehicle crashes a year at the former cloverleaf interchange. Local public safety officials say that since September 2016 there has been just one."That's incredible. One accident," said Joe Szczur, PenndDOT District 12 executive."This is different, yes. Human beings, I know, hate change and hate unusual things. But this really works," said the governor. "It shows what you can do if you apply some imagination and some hard work. There was a real need to change. As Joe said, this was a bottleneck and it was dangerous."
