In addition to the proposed widening, a roundabout was planned at the intersection with PA 662 in Richmond Township in order to reduce traffic congestion. The project, which cost $6.6 million, replaced the signalized intersection between the two routes with a roundabout, with US 222 widened to four lanes at the roundabout. Construction of the roundabout began on September 6, 2016. The roundabout opened to traffic on May 22, 2018, with all lanes at the roundabout opened on July 20, 2018. There are plans to construct a roundabout at the intersection with Schantz Road in Upper Macungie Township. Construction of this roundabout was planned to begin in February 2020 with completion by the end of 2021.
