Abstract

The proposed project is at the interchange oflnterstate 95 (I‑95) and State Route (SR) 25/US Highway (US) 17, in the city of Richmond Hill, Bryan County, Georgia. The I‑95 Southbound exit ramp currendy consists of a 16‑foot single lane that widens to three 12‑foot lanes with 6‑foot paved shoulders on the right side and 4‑ foot paved shoulders on the left side. SR 25 /US 1 7 is a four lane divided urban principal arterial, forming a ''T" intersection with the I‑95 Southbound exit ramp and northbound entrance ramp. The existing right‑of‑way (ROW) is approximately 200 feet along the centerline of SR 25 /US 17. This project proposes to increase the operational efficiency of the intersection by modifying the existing signal timing and widening a portion of the existing ramp from 16 feet to two 14‑foot lanes and then tapering to three 12‑foot turn lanes (dual lefts with a single right) with 4‑foot paved shoulders throughout the ramp. Mill and inlay is proposed on SR 25/US 17 at the I‑95 Southbound exit ramp intersection for the installation of new signal loops and signal timing modifications. The western limit of construction on SR 25/US 17 will extend to the Sommers Boulevard intersection to accommodate modifications to the signal timing due to the interconnection between the Sommers Boulevard and I‑95 Southbound exit ramp intersections. No new or additional ROW acquisition is anticipated. The proposed project is approximately 0.4 mile in length.
