This video depicts traffic movement through the Diverging Diamond Interchange (DDI) scheduled to be built at the Interstate 70 interchange with Route 19 in Washington County.

The DDI is a new type of interchange that is growing in popularity. The DDI can move traffic more efficiently compared to other interchange types.

The Pennsylvania Department of Transportation is in the process of implementing long term improvements to Interstate 70 in Washington and Westmoreland Counties. The purpose of the improvements is to increase safety and mobility. As part of the improvements, PennDOT will reconstruct I-70 between the junctions with I-79 adding a third lane in each direction and will improve the interchange with Route 19 (Murtland Avenue) in South Strabane Township, Washington County.

The current interchange at Route 19 is a substandard cloverleaf interchange that was constructed nearly 60 years ago. With the desire to minimize impacts and to account for the traffic on both I-70 and Route 19, a new interchange type was determined necessary.
