About the Project

SR 299 is an east-west high-capacity roadway that runs through Middletown, connecting US 301 with Delaware SR 1/US 13. SR 299 is essential to the residents of Southern New Castle County. The population of Middletown has increased rapidly over the last 20 years, stressing the existing roadway network. As a result, upgrades are necessary to accommodate the increasing transportation demands.

SR 299 is also Main Street in Middletown. It’s an undivided two-lane roadway that is over capacity during peak hours. Additionally, future traffic models (year 2040) show an overwhelmed corridor using the current lane design and structure. The posted speed limits along SR 299 range from 25 mph to 50 mph.

Overview

The improvements will help Middletown and surrounding communities adapt to the continued growth and expansion. This project will provide additional vehicle capacity, which will help carry the increasing traffic volumes.

Improving bicycle, pedestrian, and public transit facilities will provide residents with multiple modes of safe transportation. Upgrading traffic control devices (traffic signals, signing, and pavement markings) and adding lighting at intersections will make the road safer for all users. Take a tour of the project.
