heavy westbound to northbound right turn volume could be Enterprise Park Traffic Study t-mndled, poss~ly by use o1: an overlapping right mm arrow in the a-eric signal sequence. The dual left turns for southbound Thurston Avenue would also provide a better opportunity for the earlier .occurring peak hour volume when the Anoka Hennepin Technical College lets out its major volume of traffic The dual left turn lanes would provide additional ca~vacity at that ~ne also. A final need for the dual left turn lane is to reduce the number of times that southbound left turn ~raff~c would block the ~ront~ge road intersection which leads to Anoka Hennepin Techrrical College. The adjacent intersection to the Tac. hrffcal College ha~ an ~mod~odox stop sign arrangement currently. As t~c volumes on Thurston Avenue grow, the southbound stop sign must be removed. A left turn lane for northbound Thurston Avenue to the westbound frontage road should be provided. This could be done at the same time the dual left t-urn lanes are installed for southbound Thurston Avenue at Highway 10. . ..... Volumes on Highway 10 are also a concern. The Anoka County Comprehensive Transportation Plan (Figure A5) shows future volumes on I-Iighway 10 at Thurston Avenue of 32,500 vehicles per day. This is less than current volume, probably due to the proposed Mississippi River bridge West of Anoka. Volume west of the proposed bridge shows an increase from 21,000 ADT (1992) to 35~30 ADT in 2010. Until the proposed bridge is built, volumes on Highway 10 will continue to grow. The heavy westbound l-Iighway 10 volumes a_nd the heavy, southbound Thrrrs~on Avenue left ~ volumes will create a level of service of "F". Once the bridge is built, volumes will decrease and dis~bution will change resulting in level of service "E". Until the bridge is built, the Thurston Avenue intersection will be a major restriction to traffic flow along Highway 10. Using a s~raight tine projection of past traffic volumes, the westbound 1995 p.m. peak hour volumes estimated at 1,700 vehicles per hour will increase to 2,340 in 20 years. With full build out of .. Enterprise Park within 20 years, the intersection volumes cannot be accommodated by roadway and westbound ~raffic will face long delays. This will probably result in diversion of traffic with some traffic using Highway 47 and County. Road 116 or Enterprise Park traffic using McKinley Street. A-ANOKA9501.00 !
