Glossary
The following definitions may help your understanding of some components of the
K-61 Enhancement Project.
Access Control - The process of
limiting the number of locations that traffic can enter or exit the highway.
This is considered a major safety feature of expressways and freeways. Often, a
network of side roads links adjacent property owners to the highway.
Alignment - The curved and/or straight
line depicting the highway between two locations on a map. The actual location
of the roadway within a project corridor.
At-Grade Intersection - An intersection
of two or more roadways on the same level. Stop signs and traffic signals
usually control movement through the intersection. (See Fig. 1.)
Fiscal Year - The twelve-month period
covered by the annual budget. The fiscal year for the State of Kansas is July 1
through June 30. (i.e. Fiscal Year 2003 begins July 1, 2002 and ends June 30,
2003). The federal fiscal year is October 1 through September 30.
Grade Separation - A crossing of two
highways, or a highway and a railroad, at different levels.
Interchange - A system of
interconnecting roadways in conjunction with one or more grade separations,
providing for the movement of traffic between two or more roadways on different
levels. (See Fig. 2.)
Let to Construction - The process KDOT
follows for advertising and awarding construction projects. Construction
companies are required to "bid" projects and must be qualified to meet certain
engineering and construction standards.
Overpass - A grade separation where the
subject highway passes over an intersecting highway or railroad.
Project Corridor - The wide study
area in which the proposed roadway will be placed. The initial corridor is much
broader than the actual finished roadway alignment to allow for adjustments
during the design phase of a project due to environmental, cultural, historical
and other considerations. As design progresses, the corridor is narrowed
considerably, and only right-of-way necessary for road construction and
maintenance is acquired.
