HIGHWAY BOUNDARY CONCEPTS Part 1 - Center Line Recovery

Introduction Recovery of the Existing Right of Way Center Line is needed on every project Recovery of the Existing Right of Way Center Line is needed on every project The existing right of way is dependent on the location of the existing center line. The existing right of way is dependent on the location of the existing center line. When no new right of way is needed: When no new right of way is needed:  You need to know what are your limits. When new right of way is to be acquired: When new right of way is to be acquired:  You want to know how much land is acquired.

The Primary Element of the Highway is the Tangent The purpose of the highway is to provide a transportation route. The purpose of the highway is to provide a transportation route.

For each of these, the tangent is preferred.

Boundary Control and Legal Principles Boundary Control and Legal Principles - Curtis M. Brown - Curtis M. Brown Order of importance for conflicting elements of land location Order of importance for conflicting elements of land location A. Right of possession (unwritten conveyance) B. Senior right (in the event of an overlap) C. Written intentions of Parties 1. Call for a survey 2. Call for monuments a. Natural b. Artificial 3. Direction and Distance 4. Direction or Distance 5. Area 6. Coordinates

That which is the most obvious is of higher importance. That which is the most obvious is of higher importance. Monuments over distances Monuments over distances Distances over bearings Distances over bearings Bearings over areas Bearings over areas Tangents being less complex than curves, have higher importance. Tangents being less complex than curves, have higher importance. If there is a conflict between tangents and curves, tangents should prevail. If there is a conflict between tangents and curves, tangents should prevail. Curve definitions yield to the resolved tangents. Curve definitions yield to the resolved tangents.

The Center Line is a Mathematical Model It is not an exact match. It is not an exact match. but but

Where we had a single tangent, we should recover a single tangent

Curves should be tangent to the tangents Semi Tangent has the same bearing as the tangent

Spirals should be brought forward

Tangents Control the Curves The tangent is the primary element of the highway. The tangent is the primary element of the highway. Curves connect the tangents together. Curves connect the tangents together.

Slight change in delta angle

More common – a simple curve

Or a curve with spirals

Establishing the tangents, forces the definition for two key elements of any curve: Establishing the tangents, forces the definition for two key elements of any curve: The location of the PI. The location of the PI. And the delta angle. And the delta angle. You can either use the You can either use the Record degree of curve with a different semi- tangent distance. Record degree of curve with a different semi- tangent distance.or Use the record semi-tangent distance with a different degree of curve. Use the record semi-tangent distance with a different degree of curve.

If the curve contains spirals, there is no need to prorate the curve and the spirals. If the curve contains spirals, there is no need to prorate the curve and the spirals.
