Value Engineering on US-131
The $39 million US-131 Highway extension in Wexford County, Michigan,
involves ten miles of new four-lane divided highway from the existing
US-131 Highway north of Cadillac to north of Manton. Contractor D.J.
McQuestion and Sons anticipated that a substantial cost savings would result
from redesigning the extension before construction. They elected to
submit a Value Engineering Change Proposal (VECP). Wade Trim
reengineered the vertical profile and provided GPS data preparation
files, saving $2.4 million in earthwork. The project received a 2004 Eminent
Conceptor Award for engineering, the highest award given, from the American
Council of Engineering Companies of Michigan and the Michigan Society of
Professional Engineers.

M-25 Corridor Access Management Plan
Wade Trim prepared an Access Management Plan for the M-25 Corridor in
St. Clair County, Michigan. The corridor is experiencing steady growth primarily
from commercial development ranging from small retail service
businesses to a large shopping mall. The five-mile corridor has
16 signalized intersections and 252 access points. Wade Trim
developed the Access Management Plan with input from a Steering
Committee. We analyzed traffic, safety, land use, and other
data and prepared the final recommendation and plan following
MDOT guidelines. The Plan provides a comprehensive approach for
implementing access management techniques and principles to improve
traffic operations and safety.

South Taylor Road
Wade Trim provided traffic analysis, conceptual design and
preliminary plans to enhance a one-half mile section of South
Taylor Road to serve as a gateway to the Severance Town Center in Cleveland
Heights, Ohio. Neighborhood meetings were held to obtain input from
drivers, pedestrians and bicyclists. Traffic impacts were assessed
and recommendations were made for road reconstruction and signal timing
at the shopping center’s intersection. The project will eliminate two
lanes of traffic, add on-street parking and street lighting, widen the
sidewalk, and include decorative landscaping to create a more pleasing
corridor while maintaining traffic capacity.

Lorraine Road Extension Corridor Study
Wade Trim prepared a corridor study for the extension of
Lorraine Road from SR 64 to Rye Road in eastern Manatee County, Florida.
The rural farmland area is experiencing increasing development from
single-family residential subdivisions. Wetlands and existing homes
also posed a design challenge. The corridor study involved setting
design parameters and criteria, identifying and evaluating physical
constraints and land uses, and developing and evaluating four alternative
corridor alignments. Options presented to the County minimized
impacts to wetlands and homes. The project also involved providing cost
estimates for construction and right-of-way.

US 98 Widening
Wade Trim prepared reconstruction plans for the widening of US 98
for FDOT, District 7. The 3.5-mile segment from Suncoast Parkway
to US 19 was widened from a two-lane rural highway to
a four-lane divided highway to accommodate future traffic demands. Nearly
half of the corridor is located in the Annutteliga Hammock, a natural
area consisting of sandhill forest and scrub that has been
acquired as a Conservation and Recreational Lands project.
To minimize impacts to the environment, our design required
that the existing two lanes be milled and resurfaced to
serve as the proposed southbound lanes. Two new lanes
handle northbound traffic. The project received the 2005
Honorable Mention award from the Florida Institute of
Consulting Engineers.

US 17 (SR 35)
Wade Trim designed a 7.1-mile segment of US 17 from Arcadia to
the DeSoto/Hardee County line for FDOT, District 1. The existing
roadway, a two-lane undivided rural highway with a posted speed
limit of 55 mph, crosses three creeks; one of these is a regulated
floodway. The proposed roadway is a four-lane divided rural highway
with a speed of 70 mph, paved shoulders and ditches to convey storm
water runoff. Hydraulic studies were performed for the creek crossings
using WSPRO modeling software to conduct the backwater analysis. The
project included the design of four storm water management facilities
and preparation of signing, marking plans and traffic control plans.
Access management considerations included the spacing of median openings
and location of driveways along the highway.
