Conformance to the construction standards of the State is required for roads under that jurisdiction. To a degree, County and municipal roads and streets which are on state-aid systems also must conform to State standards. Therefore, in recommending road and street standards for Anoka County, the primary concern is for those routes under the County's jurisdiction. These standards exceed the minimum state-aid standards. In certain cases, modifications to the existing C.S.A.H. System were assumed. The widths recommended below apply to undivided roadways. The decisions to develop a divided roadway is primarily a function of the capacity requirements of intersections and the consequent need for turn lanes. However, the driving lane widths listed in the table remain applicable. Right-of-Way Widths. For the minor arterial system recommended herein, it is appropriate to anticipate the future need to provide four moving lanes on the entire System. Although it may be many years before four lanes are required in a substantial portion of the presently rural area, the cost of acquiring the additional right-of-way width before any develop- ment occurs should be very minor. Therefore, the following right-of-way standards are recommended (see Figure 13). Right-of-Way widths indicated are for widening at intersections where channelization is likely to be required. Where no roadway divider will be required because no accesses are to be permitted the right-of-way widths can be reduced.

The recommended standards apply to new construction, primarily on new alignments or where existing development does not constrain right-of-way acquisition. Where development does constrain right-of-way acquisition, a sufficient width should be acquired to allow the development of the raad- way to appropriate standards. In much of the rural areas of the County a two-lane road is all that will be required for a substantial period of time. In these cases, if.there is 39
