A new intersection design eliminates the dreaded left turn into traffic

Anyone who has ever made a left turn in a busy intersection understands that it can be a stressful maneuver. Not only do you have to wait impatiently for a break in the stream of cars coming the opposite direction, you often hold up a line of traffic, and even risk getting into a collision if other drivers aren’t following the rules of the road.

But despite how standard it may seem to turn left into traffic, that's actually not an inevitable part of driving. There's an intersection design that could save you all that trouble.

The “diverging diamond interchange” creates designated ramps that gradually direct cars to veer left or right, without ever requiring them to cross in front of ongoing traffic.

Though it might look complicated, it’s actually a simple concept. Say, for example, that you’re driving from west to east. As you come to the intersection, a red light may stop you as you let cars going the other way pass. (This is the only time streams of traffic cross each other.) If you want to turn right, a lane peels off and merges with the road carrying southbound cars. If you want to turn left, you just follow the ramp that veers to the north.

Watch it in action:

I've done this in the Denver area before. It's very easy. But I can't begin to imagine anywhere on the Shore that we have enough traffic to need it.

It would work much better if they would eliminate the two sets of stop lights...make them overpasses on one direction and underpasses in the other direction. Making people stop is the issue - perfect example is in Easton where someone is always stopped.

1:11 - the intersection of 50 and 404 would be a good candidate - but only if they make it with overpasses instead of stoplights...

Takes up a lot of real estate and if it confuses people anything like the roundabouts here well..............

I don't like this concept , it could be a deceiving racist roadway , the engineer that developed this was a conservative.

How about instead of wasting millions in taxpayer's $$$, learn how to drive.

It's not that hard folks, it really isn't.

actually why doesnt the state build an expressway to the beach while it's still relatively inexpensive farm land. tolls for those who want to use it. exits for major towns and thats it. traffic would flow much better then it does now on 50. but then the kops wont get as much speeding revenue.

3rd span straight from OC to the wesstern Shore.

7:27 and 8:23 and that would bypass all businesses hurting revenue on the shore. Smart

9:22 - people don't come here for those businesses anyway!

Thank you 9:22. Just look at Delaware rt13 after route 1. Heck look at Salisbury businesses on route 50 after the Salisbury bypass. 7:27 and 8:23, may I suggest the movie "Cars" for better understanding

its called progress. so we injure and maim how many every year on a road that has long passed the capacity forced upon it. and like salisbury is such a hub of economic activity. the ones that want to come here will. only major growth industry here any more is drugs!

too much impatience...everyone wanting/needing to go faster. I dislike the 2 sets of lights from the Shorebirds stadium 1 mile east. Even after the upgrades, awful timing during the "season", never make both lights either going east or west. Figure any aggression with traffic can be utilized beating the heck outta eating crabs!!!

Rt 50 business has to be the slowest way to get through Salisbury. EVERY light is beginning red in both directions. What genius thought up that gas waster, Gordy the Gas station guy? Old OC Road and Isabella is faster with less lights.
