Route D:
This expressway in St. Louis County runs from east of I-270 to US 67. There are at least two traffic lights along the highway.


Route M:
According to the I-55 corridor study book in MODOT's traffic information center, Route M was supposed to have been built as a freeway. Instead, it was built as an expressway. Today, the expressway in Jefferson county runs between I-55 and MO 21 / Route MM.


Junction Type of Access Speed Limit
I-55 Traffic lights at the ramps. The interchange with 55 may have at least one flyover when it gets rebuilt (eventually). 45
Catlan Road Traffic light 45
Moss Hollow Road At-grade with no turn lanes (cross road has a stop sign) 60
St. Lukes Church Rd ("private road" according to signs on the highway) At-grade with no turn lanes (cross road has a stop sign) 60
Old Lemay Ferry One-quadrant interchange* 60
Old Route M One-quadrant interchange* 60
Old Route 21 Folded diamond interchange 60
MO 21 / Rte MM Intersection road in diamond (probably future cloverleaf) 45

*David Herman explains one-quadrant interchanges: Old Lemay Ferry and Old Route M are designed as "one quadrant interchanges" according to a definition of this interchange type from MODOT.  This configuration is sort of a cross between a full interchange and an at grade intersection; through movements are grade separated (by a very large height difference at Old Lemay Ferry) but there is a T intersection on both of the routes where the two way ramp ends.  There is a stop sign at each end of the two way ramp.  This style of interchange is similar to those seen on the Blue Ridge and Natchez Trace Parkways.

MO 30:
MO 30 is an expressway southwest of St. Louis that runs from just west of I-270 to Route B. There are numerous traffic lights along this highway, which forms the center of a large corridor of urban sprawl. The speed limit is 60 mph.

Junction Log:
There is an interchange at MO 141. There were supposed to be two additional interchanges along the expressway, but both of them have been cancelled. One was to have been located in the valley between the Meramec River and I-270. The other, according to a 1978 St. Louis County road plan, was to have been built at the junction of Hawkings Summit, a short distance west of MO 141.

US 71:
US 71 has a mix of freeway and expressway segments between Kansas City and Joplin. South of Joplin, US 71 is a fully-controlled access freeway from I-44 at Joplin to south of Anderson. This freeway segment is future I-49.

From Anderson to the AR State Line, existing US 71 is under construction to become a partially controlled access expressway with at grade intersections, traffic signals, and low curb median. From the Arkansas State Line to near Brush Creek (a distance of approximately 5 miles), US 71 is finished with its upgrade. It is now 4 lanes partially-controlled access, with left-turn lanes at some intersections and traffic signals at Bear Hollow Rd, Route OO, Gordon Hollow Road and Mo Route 90. NB and SB lanes are separated by curbing &/or Jersey barriers. The only two-lane portion left is approximately 4 miles around Pineville with a scheduled completion of 2007. Future I-49 will not follow the US 71 expressway through Pineville, but instead will swing to the west as a new-alignment toll road when it is eventually built.


MO 141:
MO 141 is an expressway from just north of I-64 / US 40 to south of I-44. Further north, the Earth City Expressway and Maryland Heights Expressway, which together run from MO 364 to St. Charles Rock Rd, are part of a future northern extension of the MO 141 expressway.


MO 367:
The MO 367 expressway goes from I-270 north of St. Louis north to US 67. This is planned to be upgraded to a freeway.
