(a) The number of driveways afforded any one site shall be minimized. (The need for more than one driveway must be substantiated by a Traffic Impact Study).
(b) Access for multiple properties shall be combined, where feasible.
(c) Driveways shall be located in accordance with applicable sight distance requirements (Stopping Sight Distance (SSD) and Intersection Sight Distance (ISD) as contained in Section 200 of the ODOT Location and Design Manual).
(d) Minimum driveway spacing – based on posted speed limits -- shall be determined using the values for high speed roadways (greater than 40 mph) and low speed roadways (equal to or less than 40 mph) as follows:
High Speed Road | Low Speed Road | ||
Posted
Speed |
Minimum
Distance |

55 mph |
600 ft. |
35 mph |
250 ft. |
40 mph |
325 ft. | ||
(e) Driveway spacing shall consider the location of driveways on both sides of a roadway.
(f) Driveways shall be located where they will not cause problems with movements to and from an existing or planned street, highway, or driveway on the opposite side of the roadway.
(g) Driveways shall be located a sufficient distance from an adjacent public road intersection so as not to interfere with the traffic operations at the intersection. The following table provides the minimum acceptable distances between drive locations and adjacent intersections. For all access categories, where two roads of different access levels intersect, the restrictions and distances of the higher level roadway will apply along the lower classified roadway. (The defined distances are measured from the centerline of the intersecting road to the centerline of the proposed driveway).
Recommended Drive Distances from Intersection by Classification
Higher Roadway Classification | Distance from Intersection |
Intersecting Category I, II, or III Roadway | 600 feet |
Intersecting Category IV or V Roadway | 300 feet |
