PW CASE <br /> <br />CONSIDER THE ADDITION OF TURN LANES FOR <br />ARMSTRONG BOULEVARD AT ALPINE DRIVE <br />By: Steven J. Jankowski, City Engineer <br /> <br />Background: <br /> <br />Last fall following the completion of the Alpine Drive project between Variolite and <br />Armstrong Boulevard, the Public Works Committee requested that turn lanes on <br />Armstrong Boulevard be considered. Staff has obtained a cost estimate for full turning <br />movements, which include both right and left turn lanes (now the Anoka County <br />standard) at $108,723. This estimate includes project overhead as well as construction <br />costs. This estimate appears conservative since you may recall estimates for similar turn <br />lanes on CR 116 were $120,000 per intersection. Alternatively, if only right turn lanes <br />were designed this cost would be approximately $30,000. <br /> <br />Should either of these alternatives be desired a change order with the contractor can be <br />negotiated as the contract is still open at this time. Funding for this can be made <br />available from the City's MSA funds. <br /> <br />Recommendation: <br /> <br />Staff recommends that right turn lanes only be installed along Armstrong Boulevard. <br /> <br />Committee Action: <br /> <br />Recommend that staff order the preparation of a change order for the installation of right- <br />turn lanes along Armstrong Boulevard at Alpine Drive. <br /> <br />Reviewed by: <br /> <br />Public Works Director <br />Principal City Engineer <br />Street Maintenance Supervisor <br /> <br />PW: 03/19/02 <br /> <br /> <br />
