TraCBc on local and county roads would increase and continue to carry non-local traffic (i.e. traffic that should be on Highway 12 but uses alternate routes because of TH 12 congestion). TH 12 Alternati ve fErpresswavl Expanding TH 12 to a four-lane expressway results in traffic volumes of 36,600 in Long lake, 24,900 in Maple Plain and 20,300 in Delano. The maximum amount of traffic with an acceptable level of service is about 42,800 vehicles per day for a four-lane expressway along TH 12 - so the TH 12 Expressway Alternative is an appropriate alternative for further study. TH SS Alternative fFreewavl ifaiMing a four-lane freeway along TH 55 would divert about 8,140 vehicles per day (about 55%) from TH 12 west of Delano. The traffic in downtown Long Lake would be about 21,900 (which is an increase of 3,000 from 1988) and result in an unacceptable level of service (i.e. TH 12 would require expansion to four lanes). f*nMntv Road 11 Alternative fExpressway'i Building a four-lane expressway along CR 11 and through Medina would reduce Long Lake traffic to about 14300. Further analysis is necessary to determine if this would be an acceptable level of service without expanding TH 12. RypftiM Alternative fExpresswavl B^flMing t four-lane expressway along the South Bypass corridor would reduce Long Lake traffic to about 8,100 vehicles per day, with an acceptable level of service along existing TH 12. Therefore, this alternative is appropriate for further study. County Road 6 fExpresswav) Building a four-lane e>q>ressway along a CR 6 corridor in Orono would reduce traffic in Long Lake to about 7,930 vehicles per day, with an acceptable level of service along existing TH 12. Therefore, t^ alternative is appropriate for further study.
