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. Considerations: Considerations: Cost Cost Safety Safety Travel Time Travel Time Traveler Comfort Traveler Comfort For each of these, the tangent is preferred. 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.

ODOT Monuments are a Reference to the Center Line Yesterday’s Project Yesterday’s Project Monuments were set to monument the center line. Monuments were set to monument the center line.

ODOT Monuments are a Reference to the Center Line Do not try to connect the dots. Do not try to connect the dots. You will not end up with a straight line.

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

Other elements of the center line model Station equations are perpetuated. Station equations are perpetuated. If angle points existed, they are perpetuated. If angle points existed, they are perpetuated. Offsets from two or more different center lines are maintained. Offsets from two or more different center lines are maintained.

Monuments Control the Tangents Searching for monuments. Searching for monuments. Presume the right of way is fully monumented Presume the right of way is fully monumented Search every PC, PS, PSC, PCS and PT Search every PC, PS, PSC, PCS and PT Search for any PI that falls in the right of way Search for any PI that falls in the right of way Search the 500 and 1000 foot stations Search the 500 and 1000 foot stations Decide which monuments to use. Decide which monuments to use. Preference is given to ODOT monuments. Preference is given to ODOT monuments.

Existing Conditions

Using monuments to find the existing center line

The Highway is a Monument In the absence of Iron Rods, etc. In the absence of Iron Rods, etc. Other monuments can be used to establish the center line Other monuments can be used to establish the center line Bridges are monuments. Bridges are monuments. The pavement is a monument. The pavement is a monument. Fences are monuments. Fences are monuments.

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. Maintain the record length of the spiral. Maintain the record length of the spiral. All the adjustment may go into the curve radius. All the adjustment may go into the curve radius.

More Than One Center Line May be Needed Only the right of way on one side of the highway may be affected by a past project. Only the right of way on one side of the highway may be affected by a past project. More than one center line may need to be recovered. More than one center line may need to be recovered. Their relationship to each other will need to be determined. Their relationship to each other will need to be determined.

An Example 1945 Center Line 1932 Center Line

Another Example

Center lines may also be different end to end

Stationing Center lines from different projects are independent of each other. Center lines from different projects are independent of each other. Stationed as created – tied together with offsets. Stationed as created – tied together with offsets. Equations are brought forward. Equations are brought forward.

Center lines from different projects are independent of each other.

They are not connected together
