 The upgrade proposal proved to be very unpopular with North Kingstown residents who lived on the affected local roads . Additionally , RIDOT laid the highway out so that Route 4 would cross through wetlands in the area . This sparked environmental concerns , as one of the large wetlands that would be affected , <unk> 's Marsh , was deemed to be of high value by Rhode Island environmentalists . Despite local and environmental concerns , RIDOT still considers the Route 4 upgrade to be the <unk> way to improve traffic flow in the region . While the Department of Transportation considered upgrading nearby Route 2 to freeway standards as a potential alternative , this plan was ultimately rejected because of its effects on wells in the area . Although the project was originally scheduled to be completed by 2007 , the $ 55 million project has been postponed indefinitely .
