<br />relocated. The signal pole in this quadrant would also need to be relocated, along with an <br />extension to the mast arm. <br /> <br />Financial Impact <br />Simply adding the left turn arrows to the two remaining legs of the intersection is a relatively <br />simple modification. The signal mast arms would need to be slightly lengthened and new heads <br />added to facilitate the left turn arrow. All total, the estimated cost to modify the signal would be <br />approximately $35,000. In addition, there would be the cost of sealcoating and restriping Jackson <br />A venue. <br /> <br />The second option which includes adding a right turn lane to the southbound leg of the <br />intersection would have much more significant impacts to the signal system. In addition to <br />adding left turn arrows, the controller and the signal pole in the northwest quadrant would need <br />to be relocated and a more significant extension made to the mast arm. These modifications to <br />the signal system are estimated to cost approximately $75,000. In addition, more right of way <br />would need to be secured from the School District. Assuming this could be done at no cost, the <br />construction of the right turn lane is estimated at an additional $75,000. Therefore, this option, <br />which would provide for better intersection operation, has a price tag of approximately $150,000 <br />plus the cost of sealcoating and restriping of J ackson Avenue. <br /> <br />Both School Street and J ackson Avenue are eligible for the use of Municipal State Aid funds. <br /> <br />Attachments <br /> <br />.
