Use of either full clover leaf system or multilevel interchange structures at junctions is not yet generally accepted in Great Britain; two level roundabout design with roundabout carried over highway by two bridges and connected to it by system of slip roads; 500-ft minimum length for accelerating lanes and for decelerating lanes 400 ft is acceptable; 3-mi minimum spacing of junctions and maximum 12 mi are desirable but in future average 7 mi spacing is likely.
