Project Description
This project
consists of upgrading US 45 from two to four lanes from IL
142 in Eldorado (Saline County) to IL 141 at the
Gallatin/White County line. The project, approximately 9
miles in length, will construct a five-lane urban section
from the southern terminus to Dewey Road, where the center
turn lane will be replaced with a grass median to the
project’s northern terminus. The existing two-lane section
will primarily be used to carry northbound traffic, with two
new lanes constructed on the west side of the existing
pavement to carry the majority of southbound traffic. New
lanes will be constructed to the east of the existing
roadway for a portion of the project that traverses the
North Fork Saline River floodplain to minimize impacts to
the copperbelly water snake habitat on the west side of the
existing roadway in this area. The purpose of the project is
to improve regional connectivity and promote economic
development in an economically depressed portion of
Illinois.
Environmental Assessment
The project’s
Environmental Assessment (EA), containing the final analyses
and reporting on the preferred alternative, was approved by
the Federal Highway Administration (FHWA) on April 18, 2011.
On June 22, 2011 the FHWA agreed that the project would not
result in a significant impact to the human environment and
issued the Finding of No Significant Impact (FONSI). The EA
and the FONSI may be viewed by clicking the links below:
