other uses as well. They generally connect traffic from Collector roads and local streets and
distribute them to Principal Arterials, Expressways, Freeways, and some Interstate roads. They
normally carry lower volumes of traffic than Principal Arterial roads.
Major Collector roads can be two or three lanes that collect traffic from local streets and distributes
them to Minor or Principal Arterials. They serve mostly residential land use but could also serve
commercial, industrial, and other land uses. They normally carry lower traffic volumes than Minor
Arterial roads. Major Collectors most often are found in more urban densely developed areas.
Minor Collectors are two lanes that carry traffic from side roads and adjacent land use to higher
classified roads. They normally are found in rural areas that have limited land use activity.
B-2. MoDOT Roads
The Missouri Department of Transportation maintains the most major roads in the County and those
with the highest functional classifications. These roads include Interstates like I-70 and I-64 and
Freeways, Expressways, and Principal Arterials such as U.S. 40/61, U.S. 61, U.S. 67, Rt. 79,
Rt. 94, Rt. 364, and Rt. 370. All lettered roads are either Principal Arterials, Minor Arterials, or
Major Collectors, and are maintained by the state with only few exceptions. Rt. 94 in the City of
St. Charles is carried over city streets from Kingshighway to south of Rt. 370 and Rt. M north of I-
70 is carried on Main St. through old O’Fallon to Rt. P. Some lettered roads like Rt. K are Principal
Arterials that pass through highly developed commercial and residential areas. Others include Rts.
A, B, C, D, F, H, J, N, P, T, V, W, Y, Z, and DD. These roads carry higher amounts of traffic than
other county roads and serve all parts and land uses in the County.
B-3. County and City Roads
All roads that are not state highways are maintained by the County or cities. According to the St.
Charles Master Plan, the County Highway Department maintains 640 miles of roads. They handle
a few for smaller communities, under contract, with funds from the County Road and Bridge Fund.
Most cities maintain their own roads using various funding sources. New projects are funded using
local funds, funds from the ½ cent transportation sales tax, and federal funds. The goals and of the
County for maintaining and improving roads are contained in the County Master Plan.
In addition to the County’s Master Plan, St. Charles County has a Proposed Ten Year Transportation
Improvement Program. The present document was adopted by the County in December 2003 and
is for FY 2003 to FY 2013. It contains a list of planned road improvements by the major
municipalities and by the County. Although all the projects may not presently have funding, it is
a list by which the County can plan road improvements for future years. From this document, the
County develops a three-year Transportation Improvement Program (TIP) that consists of funded
improvements planned for the next three fiscal years, starting January 1, of each year. Funding for
these projects comes mostly from the transportation sales tax revenue. Some may be included in the
Council’s TIP and receive a percentage of federal dollars from various funding categories. The
County’s present TIP is for FY 2007 through 2009 .
