KDOT Access Management Policy
4.2.1 Full access control
This classification addresses all current and future freeway sections. Access to the highway is only
permitted via grade-separated interchanges (Figure 4-11). Access control will be extended down
intersecting roadways so that adjacent side road intersections do not interfere with interchange
operations. Guidelines for interchange spacing can be found in KDOT Standard Operating Manual
(SOM) 1.12.2.

• Desirable interchange spacing will be a minimum of 4 miles apart in rural areas and 2 miles
apart in urban areas.
• Access control along the intersecting roadway ideally will extend one-half mile from the ramp
intersection to the nearest full movement side road intersection or access point. If a traffic
study shows that the distance on the side road from an on- or off-ramp to a full-movement
intersection should be more or less than one-half mile, this information should be taken into
consideration before a final decision is made.
• All new bypasses should have full access control.
• Examples include I-70, I-35, I-135, portions of US-69, US-59 between Lawrence and Ottawa,
US-400 SW Dodge City Bypass, and US-36 in Doniphan County.
