St. Charles County Transportation Plan 2030 - East-West Gateway ...

Mueller Rd., Elm Point Rd., and Little Hills Expressway to Rt. 94. Old industrial development has
declined along Rt. 94 in the north part of the City of St. Charles. South of I-70 along Rt. 94, some
additional commercial development has occurred south to Rt. 364.
Section 3 - St. Peters runs from Section 2 on the east to Rt. 79 and its southern extension, Salt
Lick/Birdie Hills Rd. on the west. It runs west along Rt. N and then south along Rt. K and southeast
along I-64 to the Missouri River. It is mostly flood plain north of I-70 and east of Rt. 79. From I-70
south past Mexico Rd. there is a large amount of old residential development with newer
development occurring in the west end of the Section along Salt Lick/Birdie Hills Rd. Further south
there is newer residential development. New development has also occurred in pockets along Mid
Rivers Mall Dr., Spencer Rd., Willott Rd., and Jungermann Rd. Approaching Rt. 94 there are
considerable undeveloped areas which are fast turning into new subdivisions. Southeast of Rt. 94
to the Missouri River there are considerable farms and undeveloped land that are being turned into
residential development. The most intense use is south of Rt. 364 all the way to I-64 between
county roads such as Jungs Station, Caulks Hill, Pitman Hill, Wolfrum, and Independence. This area
has seen a very dramatic increase in residential development over the last ten years.
Commercial development has continued, adjacent to all major roads in Section 3, with rapid
development along Salt Lick Rd. around I-70 and south to Mexico Rd. The southern part of Mid
Rivers Mall Dr. from Willott Rd. to Rt. 94 has seen a substantial increase in commercial
development with the most notable being from north of Central School Rd. to Rt. 94. Commercial
development has grown along the southern part on Rt. 94 all the way from Harvester Rd. to I-64.
A considerable amount of undeveloped land has been converted to commercial use along many parts
of this road and it is anticipated, because land is so abundant, that the remaining undeveloped areas
adjacent to the road will also be turned into commercial development of some type. Substantial
commercial development has occurred just north of I-64 between Rt. K and Rt. 94 and continues
north along Rt. K. Industrial development in Section 3 has been confined to the area in the northeast
quadrant of I-70 and Rt. 79 and to the north of I-70 at Mid Rivers Mall Dr.
Section 4 - Wentzville-O’Fallon runs from Section 3 on the east, along I-64/U.S. 40/61 on the south,
along with Rt. N, west to the Warren County line. The north boundary is Lincoln County. It
contains a considerable amount of old residential development especially along I-70 around old
O’Fallon and in the Lake Saint Louis area. East of Rt. M in old O’Fallon, and north of I-70 to Rt.
79, considerable new residential development has occurred fed by the new T.R. Hughes Blvd.
interchange on I-70. New development has occurred to the north along Rt. P from Rt. M west to St.
Paul, Josephville, and Flint Hill. On the south side of I-70, new residential development has been
prolific to the east and west of Rt. K all the way south to I-64 and westward toward Lake Saint Louis
filling in much of the undeveloped area. Development has grown dramatically south along Bryan
Rd. from its interchange at I-70 south to Winghaven Blvd. at Rt. N. A very large amount of
undeveloped land still exists in this area, especially south of the corridor for proposed Rt. 364 and
it is expected that it all will be converted into residential development as time goes on. The area
