*Minimum length of tangent between curves in opposite directions (reverse curves). Reverse curves without tangent sections between curves are not permitted, except on local streets.

**Minimum length of tangent at intersections is measured from the Right-Of Way line of the intersecting street. Tangents approaching an intersection may vary in length with increased design speed.

***As determined by the Town Engineer.
