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

Jungermann Rd.
This road runs from Veterans Memorial Pkwy. to Rt. 94, 3.5 miles and has 10 signals. Speed runs
were not conducted on this road by the Council, but observations reveal that it is operating without
excessive congestion. Traffic volumes are around 30,000 south of Mexico Rd. and decline
southward to about 20,000 north of McClay Rd. The signals are operating at LOS D during the peak
hour periods except for the one at Mexico Rd. which is operating at capacity, LOS E. Travel on this
road is estimated to be LOS D.
Muegge Rd.
This road has four lanes from Mexico Rd. south to Old Hwy. 94 and the ramp connections to Rt.
364. It handles about 16,000 vehicles per day. Speed runs were not conducted on this road. It has
seven signals not counting Mexico Rd. Observations indicate they all operate at or below LOS C
during both the am and pm peak hours and the road operates at LOS C.
Bryan Rd.
This five-lane road runs from I-70 to Rt. N where it becomes Winghaven Blvd., a four-lane parkway
to U.S. 40/61. No speed runs were conducted on this road, however, it has six signals that all
operate at LOS C during the peak hour periods. It carries about 25,000 vehicles per day and
observations indicate it is has no serious congestion and operates at LOS C.
Truman Rd.
This five-lane road runs from I-70 to Rt. 370, has three signals, and handles about 14,000 vehicles
a day. It is two miles long to the I-70/Cave Spring Rd. interchange. No speed runs were made on
this road but observations indicate it is operating at LOS C during the peak hours except for traffic
at the north service road of I-70 that operates at LOS E.
Mexico Rd.
This five-lane road runs from Veterans Memorial Pkwy. just east of Muegge Rd. to Bryan Rd., a
distance of 10 miles. It handles about 35,000 at Jungermann Rd., 30,000 from Mid Rivers Mall Dr.
to Rt. K, and 12,000 east of Bryan Rd. It has about 18 signals, some at school entrances. No speed
runs were made on this road but observations suggest it could be divided into three different
segments. The east segment would be from Muegge Rd. to Mid Rivers Mall Dr., the central from
there to Rt. K, and the west segment from Rt. K to Bryan Rd. The east segment operates at LOS D
during the peak hours due to close signals and their operations. The central part operates at LOS
C with the signal at Mexico Rd. providing LOS D during the peak hours. The west segment’s most
critical issue is the signal at Rt. K but it operates at LOS D even during the peak hours. Traffic flow
between signals is good at LOS C and as noted above dictates the roads LOS at these points.
B-5.4. Minor Arterials
Minor arterial roads can be two, three or four lanes and serve traffic for shorter distances. They
connect traffic from collector roads and local streets to Principal Arterial roads. They serve adjacent
