What guarantee of access to 336 would residents and businesses have where construction of the new road eliminates the existing highway?
Every attempt will be made to provide access to the properties adjacent to the proposed highways. This may be direct access or through another public road. If we cannot provide access to a property, it will be purchased as a landlocked parcel.
Expressways are constructed as partial access controlled facilities. This means direct access is allowed for single family residence and field entrances and public roads may be at-grade intersections. Also, interchanges are constructed or planned at most marked routes or high-volume county highways. Commercial properties are not allowed direct access and are brought in off of public or frontage roads. A similar facility would be US 67 between Monmouth and Macomb.
Farm machinery is not allowed to be driven on a freeway. Farm machinery would need to be driven on side roads or frontage roads to access fields. With an expressway, farm machinery is allowed to be driven on the highway and field access is generally allowed along the main highway. No exceptions to these general rules are allowed.
How would intersections of 336 and county highways or township roads be handled? Stop and cross? Bridge? Dead end? If different treatments are possible, how does IDOT make these decisions?
The intersections of IL 336 with county highways and township roads will be handled differently depending on a freeway design or an expressway design. With a freeway design, no at-grade intersections are allowed with the four-lane highway. A county highway or township road could go over or under the freeway, connect to the freeway with an interchange or be closed at the freeway. IDOT will look at safety, traffic, access, cost, adverse travel and talk with the roadway "owner" to make the decision. With an expressway design, at-grade intersections are allowed with the four-lane highway. A county highway or township road could go over or under the expressway, connect to the expressway via interchange or intersection, or be closed to the expressway. IDOT will look at safety, traffic, access, spacing of access, cost, adverse travel and again talk with the roadway "owner" to make the decision.
There are advantages and disadvantages to both types of design. Future development along freeways does not generally cause the increase in congestion and accidents because of no direct access which is not the case with development along an expressway. However, freeways are generally more expensive and disruptive to construct because more frontage roads and bridges are usually required at the time of construction.
We are currently looking in detail at each type of facility throughout the corridor. The impacts of each type can be very similar in some areas and very different in others. Once the details are developed, we assess the advantages and disadvantages for various sections of the route. We intend to present the preferred facility type in each section, plus several alternative alignments, in the next public information meetings being planned for later this year. After receiving input, alignments will be further refined and a facility type(s) will be selected.
With either type of facility, expressway or freeway, public road access to properties will be maintained. Part of the study is to do an analysis to determine how best to provide access to all the properties. Options include constructing frontage roads, constructing new bridges carrying existing roads across the new highway, or in some cases, constructing the new highway over existing roads. The decision as to which highway type will be recommended will be based on, but not limited to, the following general criteria:
The anticipated beginning of the actual construction phase of IL 336 cannot be determined at this time because no funding is available for land acquisition or construction in the Departmentís multi-year highway program. The current planning study is completely funded and we anticipate completion in the Fall of 2008. Additional funding for a portion of the design phase is available in the multi-year highway program which will be used for soils investigation studies and design plan preparation. It would take approximately three years from completion of this study before a section of construction could begin assuming funding for land acquisition and construction are in place.
