State Transportation Improvement Programs. Transportation programs
identify actual improvement projects as well as funding and schedules for
Illinois law requires IDOT to develop five-year proposed improvement programs
for highways, public transportation, airports, and rail modes.
The highway edition includes state and federally funded highway projects on the
state and local system (five years of state and three years of local highway
projects). In addition, after the completion of the state transportation budget,
an annual highway improvement program is published that updates the first year
of the five-year program.
The public transportation edition contains capital projects for a five-year
period, with projects in the first year specifically identified. The first year
of the program also includes expected operating expenditures.
Each spring, the Governor submits the five-year improvement programs for
highways and public transportation to the Illinois General Assembly. At the same
time, the programs are distributed to local governments, citizens and interest
groups for review and comment prior to the adoption of IDOT's budget. IDOT also
issues news releases when appropriate. The published five-year programs include
a form and telephone numbers for the members of the public to submit their
comments to IDOT. All comments received are documented and taken into
consideration in the subsequent development of a three-year program required by
the federal government.
The three-year Statewide Transportation Improvement Program
(STIP) is required by the federal Intermodal Surface Transportation Efficiency
Act. It contains all federal and state-funded highway and public transportation
projects proposed in Illinois over a three-year period. Regionally significant
projects are identified individually while other projects are grouped.
IDOT publishes a draft STIP after the General Assembly approves the annual state
budget. The draft STIP also includes an invitation to the public to review the
document and submit comments via the enclosed form or calling the listed
telephone numbers. This is accompanied by the publication of display ads in
newspapers throughout the state and a statewide news release informing the
public of the availability of the draft STIP at IDOT offices and through the
Illinois Document Depository Libraries.
The comments received on the draft STIP are then taken into consideration in the
development of the final STIP.
If significant changes are made to the draft STIP, such as program emphasis and
the addition or deletion of regionally significant projects, IDOT will publish
notifications of the amendments in the newspaper with the predominant
circulation in the area impacted by the change.
