Randall at U.S. Route 20 Feasibility Study
Project Overview
KDOT has selected the team of CDM Smith to complete a Feasibility Study
on the Randall Road and US 20 interchange and its surrounding
intersections.
The grade-separated Randall Road interchange with US Route 20 and its
adjacent intersections serves a diverse range of travel demands and
access. The existing configuration reflects prior design priority
towards through-flow on US 20 (26,000 ADT), but Randall Road (48,000
ADT) clearly now has a greater demand for capacity and has become
increasingly entangled in congestion as yearly traffic demand continues
to climb. Similarly, Larkin Avenue (17,000 ADT), built originally as a
local road, now handles a much higher ADT serving as the southern
gateway to Elgin and the most direct hospital access for communities to
the west and south. As regional and local traffic patterns have evolved
several geometric and operational design deficiencies at and adjacent to
this interchange have become exacerbated.
KDOT recently completed construction of the Randall & Weld/US 20
project which disconnected local access to Weld Road and while this
project has reduced delay along Randall through Elgin, the goal of this
Feasibility Study at Randall Road and US 20 is to explore a correction
of geometrics, operations and safety which may require a partial or
complete reconfiguration of the interchange. It is the beginning of the
process of addressing a long-term wide-range geometric solution that
solves congestion issues and reduces the overall demand on driver
decision-making.
The key elements of this project are to address increased traffic
volumes and access demand and competing jurisdictional interests within
the compressed footprint. The Feasibility Study will continue until the
Spring of 2021. At that time it is KDOT’s goal to have gained consensus
with key stakeholders and developed feasible alternatives to bring this
project into a Phase I Engineering Study with a shared vision of land
use and road/bridge function. This study hopes to address numerous
issues and so a fair amount of time will be spent studying driver
origin/destination data within the project limits.
