Homeowners at the Newtown-Monroe border are raising concerns over a proposed 11-unit apartment complex at South Main Street and Swamp Road. Residents fear the project, which includes three low-rise buildings and a one-bedroom ranch, will exacerbate traffic issues at a problematic intersection. Despite the developer’s plan to add a “Welcome to Newtown” sign, local residents are worried about increased congestion and safety risks. The town’s Planning and Zoning Commission will address the concerns in a public hearing scheduled for Thursday.
