.� Page 21 Honorable Mayor and City Council April 12, 1978 City of Orono Box G6 Crystal Bay, 2�tinnesota 55323 Re : Ring Route Alternate Evaluation Our File No. 139 feet long (.99 miles) . No detailed engineering studies have been made of the design of the alternate route so estunated construction costs are not available. Assuming construction of the alternate route was similar to the proposed route, a rough cost estimate based on proportional length ��ould be about $570,000, an increase of about 13%. The proposed roate is designated as a 2•iunicipal State Aid (I•ISA) street. 'I'his designation �aould have to be reassigned to the alternate route for construction. The increase in length, 0.11 miles, is more than the 0.07 miles the City has available to designate for MSA streets, It would be necessary to revoke some other I�fSA designation on an existing street in order to do this. Town Line Road bet�.reen Co.Rd. 6 and T.H. 12 is a narrow gravel roadway, de- ficient in width, cross-section and grade. In order for the ring route con- cept to become worlcable, Town Line Road would have to be reconstructed. The _ length is approximately 3,750 feet (.71 miles) . Ass�ing si.milar construc- tion to the proposed ring route, a rough estimate of cost based on proportional len�th y�ould be about $410,000. In addition, there is a very narrow bridge at the railroad tracks south of T.H. 12 which would have to be replaced. This bridge would cost in excess of $300,000 based on today's prices.. In order for the ring route concept to work, for it to draw off traffic from Co.Rd. 15; a continuous route on an improved paved roadway is necessary. Town Line Road lies within three different cammunities. The City of Orono does not have the financial capability of constructing the entire route from Co.Rd. 19 to T.H. 12. �This cost would be in the magnitude of $1,280,000. Hennepin County has indicated that they are not able to construct this facility �aithin the foreseeable 'f�ture. We have attempted to reduce the various elements of comparispn between the proposed route and the alternate route to a point system, which is outlined on the attached sheet. It must be pointed out that this quantitative number system is very subjective. The danger in this kind of approach is that the various categories do not necessarily carry the same weight, although they have been given the same number rating. For example, if the "construction" and "User Factors" items are twice as important as the others, the "scores" difference �aould change from 55-43 to 75-53 in favor of the proposed route. Tt►is very general review of the �ahole ring route concept did not permit a more sophisticated analysis. Page 2.
