The bridges to be closed and dates of closure are as <br /> follows: <br /> - CSAH 15, Tanager Lake Bridge will be closed from April 4 until <br /> mid-sun��ner. The detour route will be CSAH 51, CSAH 146, and TH 12. • <br /> - CSAH 19, Coffee Bridge will be clos2d from April 16 until approximately <br /> July 15. The �etour route �vill be via CSAH 51 and CSAN 15. <br /> - CSAH 51, Noerenberg Bridge will be closed from approximately July 15 <br /> until approximately Septe,-nber 15. The detour route �aill be via CSAH 15 <br /> and CSAH 19. <br /> The Coffee and Noerenberg bridges cannot be ciosed at the same t�me. <br /> Tanager Lake bridge closure has spurred the concerns of Oi�ono and Long Lake <br /> as to potential traffic preblems on CSAH 146, particularly at Fox Street, and <br /> on TH 12 at the intersection of CSAH 146. A four-tivay stop has been requested <br /> by neighborhood petition at the former intersection. Signal r�odificaiio�s in � <br /> the form of a left turn pnase for westbound TH 12 traffic at CSAH 146 has be2n <br /> suggested by Long Lake officials (Mayor Gallagher and Councilman Todd Heglund). <br /> - The following actions have been or will be taken in response to these concerns: <br /> 1) The entire detour route will be closely monitored following the closure <br /> of CSAH 15 with appropriate response to problem locations. Particular <br /> . -atte�tion will be concentrated on the two subject intersections. <br />, 2) D1n/DOT is being requested to increase the green time on TH 12 at CSAH 146 <br /> to help provide for the westbound traffic surge and increased westbound <br /> to southbound left turn. Also requested is the early striping of TH 12, <br /> I ' hopefully nrior to the detour. <br />� 3) Studies and observations by both Mn/DOT and the county will be scheduled <br /> after the detour goes into effect. This will determine the extent of any <br /> necessary improvements such as a left turn phase at the signal . <br /> Emergency protection and community circulation are the major concerns of Orono <br /> in conjunction with the Coffee and Noerenberg bridge closures. On h1arch 28 <br /> i I met with Orono Police Chief Kilbo and the fire chiefs of Mound, 6�ayzata, <br /> Long Lake and �1aple Plain (Orono contracts all fire protection within their <br /> city to those four agencies). By using alternate routes and reassigning <br /> coverage districts all sections of the city will have adequate rire protection. <br /> The fire chiefs expressed some cc�ncern but they felt the problem vras certainly <br /> not insurmountable. The chiefs t��ere very cooperative in this reassignment. <br /> In fact, they indicated that the reassignments and rerouting plan will go into <br /> effect as soon as possible, not necessari�ly 4�aiting until April 16 when the <br /> Coffee bridge is closed. A representative of the North hlemorial Ambulance <br /> Service also attended the meeting. <br />� . <br />
