(a)

1. (1) Although access approval may not be needed, coordination with the Arkansas Division of the Federal Highway Administration is recommended to determine if any analysis is required based on the context of the project.
2. (2) If it is determined these changes may require an analysis of the planning, environmental, design, safety, or operations of the proposed improvements, the Arkansas Department of Transportation will coordinate with the Arkansas Division of the Federal Highway Administration to determine the type and extent of analysis required.

(b) The following changes to freeway facilities may not require approval under this part:

1. (1)

   1. (A) Shift of a ramp’s location within the same interchange configuration, which results in ramp spacing that meets the Federal Highway Administration’s design criteria.
   2. (B) If the interchange is reconfigured in such a way that the travel patterns change with the same number of access points, coordination of the project should be performed with the Arkansas Division of the Federal Highway Administration to determine the type of review.
   3. (C) Changing the location of a ramp could result in changes to the safety and operational performance of the freeway system;

2. (2)

   1. (A) Addition of lanes to an on-ramp may not require a freeway system access change request be submitted.
   2. (B) However, based on coordination with the Federal Highway Administration, analysis of the potential consequences of this change on the safety and operational performance of the freeway may be required;
3. (3) Addition of left-turn storage lanes, right-turn storage lanes, and through travel lanes at the terminus of existing ramps;
4. (4) Relocation or shifting of the existing on-ramp or off-ramp termini, i.e., moving the ramp end that connects with the local road, along the same roadway;
5. (5) Addition of a single auxiliary lane between two (2) adjacent interchange ramps where the single auxiliary lane does not function as a mainline travel lane;
6. (6) Modification of the length of acceleration or deceleration lanes involved with any ramp;
7. (7) Improvement of traffic signals at ramp termini with local roads do not require approval but should be reviewed to ensure that the changes in the signalization do not result in queue spillback into the mainline lanes of the freeway and that sufficient storage is provided;
8. (8) Implementation of ramp metering or other active control of vehicles entering the freeway system;
9. (9) Construction of new signing, striping, and/or resurfacing of a freeway on-ramp or off-ramp where geometric features are not changed;
10. (10) Installation of roadside guardrail and concrete barriers such as for resurfacing and safety projects;

11. (11)

    1. (A) Construction of overpasses or grade separation structures without ramps along freeway facilities.
    2. (B) The approval of air-rights over freeway facilities is addressed as part of the location and design concept acceptance with the National Environmental Policy Act of 1969, 42 U.S.C. § 4321 et seq., process and approval of plans, specifications, and estimate; and
12. (12) Changes in access between managed lanes and general purpose lanes on the freeway.
