PROJECT DESCRIPTION: Smithton Development Company, LLC employed our firm
to prepare the Traffic Study, Intersection Design Study (IDS) and Construction
Plans, Specifications, and Estimate for the intersection of a new subdivision
entry roadway (Stonefield Drive) intersecting an existing state highway (IL
Route 159). All phases of the project were subject to IDOT review for
compliance with IDOT standard policies and procedures. The Traffic Study was
completed using the Trip Generation Manual to develop traffic forecasts. The
IDS analysis was completed using Highway Capacity Software (HCS). Turning
movements and corner radii were developed using AUTOTURN software for the
appropriate design vehicle, and the intersection sight distance was checked.
The project included the addition of a left-turn lane and right-turn lane on IL
Route 159. The construction scope included asphalt widening and paving, asphalt
shoulders, ditching, drainage culverts, thermoplastic pavement markings and
driveway removal and replacement. Our firm was also retained to provide all
land and ground surveys, bidding assistance, construction staking and
construction testing services.
