(605 ILCS 5/4-403)
(from Ch. 121, par. 4-403)
Whenever local traffic conditions within any municipality
through which or to the corporate limits of which any State highway is
located, in the discretion of the Department, are such as to interfere with
or impede through or State traffic, the Department is authorized and
directed to locate and construct a durable hard-surfaced highway in the
nature of a belt-line to connect State highway routes entering such
municipality, so as to avoid congested traffic districts in the
municipality. Such belt-line routes may be wholly without the corporate
limits of the municipality or partly within and partly without such limits.
The type of construction and width of such belt-line routes shall be
sufficient to care for present or reasonably expected future needs of
through or State traffic.
Such belt-line routes shall be a part of the State highway system.
