Please review each of the alternative illustrations and the Decision matrix below to see the comparison of engineering and environmental criteria evaluated. After reviewing, be sure to click on the button at the top of the webpage to Provide Your Input.

Alternative A

• US 30 Mainline has three lanes in each direction.
• The interchange configuration in Alternative A is similar to the current interchange but with larger loop ramps.
• US 30 Westbound Ramps intersect US Route 322 at a signalized intersection.
• US 30 Eastbound Ramps intersect US Route 322 at a signalized intersection.
• Lloyd Avenue is relocated to intersect US Route 322 opposite Rock Raymond Road at a signalized intersection.
• The current Lloyd Avenue alignment terminates at the Park and Ride access.
• The existing full movement access to Royal Farms remains as a stop-controlled intersection, with removal of the existing signal since Lloyd Avenue is relocated.

Alternative B

• US 30 Mainline has three lanes in each direction.
• The interchange configuration in Alternative B is a Diverging Diamond Interchange (DDI).
• A key feature of the DDI is that it creates two signalized crossover points which eliminates the need for left-turning vehicles traveling onto or off the interstate to cross paths with approaching through vehicles.
• Two traffic signals are provided along PA Route 340 at the crossover points for eastbound and westbound movements.
• Lloyd Avenue is relocated to intersect US Route 322 opposite Rock Raymond Road at a signalized intersection.
• The current Lloyd Avenue alignment terminates at the Park and Ride access.
• The US Route 322 Royal Farms access permits only right-in and right-out movements and the traffic signal is removed.

Alternative C

• US 30 Mainline has three lanes in each direction.
• The interchange configuration in Alternative C is a Single Point Urban Interchange (SPUI).
• A key feature of the SPUI is that it provides a single central signalized intersection through which all left-turns utilizing the interchange must travel.
• Lloyd Avenue is relocated to intersect US Route 322 opposite Rock Raymond Road at a signalized intersection.
• The current Lloyd Avenue alignment terminates at the last property owner.
• The existing full movement access to Royal Farms remains as a stop-controlled intersection, with removal of the existing signal since Lloyd Avenue is relocated.
