Purpose

The Oklahoma Department of Transportation (ODOT) will host an in-person public meeting for the intersection modifications of US-377 and SH-22 in Tishomingo, Oklahoma. The public meeting will include a presentation of the three design alternatives at 5:30 pm. The purpose of the public meeting is to solicit feedback from the public on the presented design alternatives and provide an opportunity to speak with professionals involved with the project. The information will be available beginning April 23, 2024, and comments are requested by May 7, 2024.

Description

ODOT, in cooperation with the Federal Highway Administration, proposes to make intersection modifications to the US-377 and SH-22 junction west of Tishomingo, Oklahoma. The existing US-377 and SH-22 are 2 lane highways that junction at a Y-intersection. The purpose of the project is to improve safety and operational efficiency of the intersection.

Three alternatives are being considered for the intersection, and they are named as follows: Four-Legged Intersection; T-Intersection; and Roundabout Intersection. The three alternatives are described below.

Alternative 1: Four-Legged Intersection

This alternative consists of realigning the northbound leg of US-377 and creating a four-legged, unsignalized intersection with SH-22 and Western Avenue. Each approach would include a left turn lane, and the eastbound and westbound approaches would also have right turn lanes.

Alternative 2: T-Intersection

This alternative consists of realigning the eastbound leg of SH-22 and creating a T-intersection with US-377 which would be unsignalized. Each approach would have dedicated turn lanes.

Alternative 3: Roundabout Intersection

This alternative consists of realigning each leg of SH-22 and US-377 to create a three-legged roundabout in the center of the existing Y-intersection.

Modern Roundabouts are a common form of unsignalized intersection in use throughout the world. In a roundabout intersection, one-way traffic moves around a central island, and entering traffic must yield to circulating traffic. Modern roundabouts maximize safety by significantly reducing conflict points and minimize traffic delay since traffic does not have to take turns to use the intersection like at a traffic signal. Roundabouts are also more cost effective than traffic lights as they eliminate hardware, maintenance and electrical costs associated with the signals.

Environmental Studies studies are being conducted within the study area to identify potential environmental impacts that could result from the proposed project. The studies considered streams and wetlands, federally listed threatened and endangered species, habitat for protected birds, hazardous materials, and cultural resources. Partly due to the fact that the area is already in use as a transportation facility, this project is not expected to have significant environmental impacts.
