Project Info

To reduce congestion and improve safety at the I-83 corridor in Shrewsbury, Kinsley was selected to build a new Diverging Diamond Interchange (DDI) on SR 851. Our scope of work included:

• Replacing the existing, three-span I-83 bridge over SR 851 with a two-span bridge
• Lengthening and reconfiguring the ramps leading on to and off of I-83
• Replacing the culvert that carries Deer Creek beneath the interchange with a 14-foot-wide by 400-foot-long precast box culvert, which required sheet pile shoring up to 46-feet-deep
• New traffic signals at the interchange
• Pile-driving 4,800 linear feet of foundation bearing piles for bridge foundations
• Numerous stream relocations
• Improving the stormwater management system, including installation of 67 storm inlets, 3,200 linear feet of storm sewer systems, three stormwater facilities and 1,300 linear feet of curbing
