Where possible, accesses on opposite sides of the street should be lined up directly
across from each other. Sometimes this is not possible due to site restrictions or
property lines. If accesses cannot be lined up across from one another, the preferable
offset is so that left turns entering each respective access do not overlap. Table
3 shows the minimum offset for intersections on opposite sides of the street when
the potential for overlap does occur. However, a traffic impact study may determine
that a larger offset is required depending on the level of queuing that may occur
at the intersections.
Table 3. Minimum Access Offset Requirements
Street Classification
Minimum Offset (feet)
Arterial street
310
Major collector
180
Minor collector
120
Local street
n/a
Notes:
1. These values are a minimum requirement and are subject to change based on the results
of a traffic impact study.
2. Offset requirements are not applicable in the case of RIRO accesses such as when
a raised median is present. Access should only be provided to arterial streets when
reasonable alternative access is does not exist.
