The parkways authority shall have authority to construct grade separations at intersections of any project with public roads and state highways and to change and adjust the lines and grades of such roads and highways so as to accommodate the same to the design of such grade separation. The cost of such grade separations and any damage incurred in changing and adjusting the lines and grades of such roads and highways shall be ascertained and paid by the parkways authority as a part of the cost of such project.

If the parkways authority shall find it necessary to change the location of any portion of any public road or state highway, it shall cause the same to be reconstructed at such location as the parkways authority shall deem most favorable and of substantially the same type and in as good condition as the original road or highway. The cost of such reconstruction and any damage incurred in changing the location of any such road or highway shall be ascertained and paid by the parkways authority as a part of the cost of such project.

Upon the request of the parkways authority, the commissioner of the state department of highways shall relocate or discontinue any road or highway over which he has authority and control which is affected by the construction of any project.

In addition to the foregoing powers, the parkways authority and its authorized agents and employees may enter upon any lands, waters and premises in the state for the purpose of making surveys, soundings, drillings and examinations as it may deem necessary or convenient for the purposes of this article, and such entry shall not be deemed a trespass, nor shall an entry for such purposes be deemed an entry under any condemnation proceedings which may be then pending. The parkways authority shall make reimbursement for any actual damages resulting to such lands, waters and premises as a result of such activities.

The state of West Virginia hereby consents to the use of all lands owned by it, including lands lying under water, which are deemed by the parkways authority to be necessary for the construction or operation of any project.
