<br />CASE #4 <br /> <br />CONSIDER HIGHWAY 10 MEDIAN OPTIONS AT LICENSE BUREAU ACCESS <br />By: Steven Jankowski, City Engineer <br /> <br />Background: <br /> <br />Concern has been raised over the number and severity of the accidents on Highway 10 at the <br />median opening opposite the County Licensing Bureau on the north side of the highway. Lano <br />Equipment is also located at this median on the south side of the highway. Attached to this case <br />is a summary of the accidents which have occurred at this location since 2003 along with the <br />individual accident reports. Over this period there have beel1 ten reportable accidents (causing <br />personal injury or property damage greater than $1,000). This includes one fatality. In addition <br />there have been six accident reports involving minor damage. Three fourths of. the accidents <br />involved the median opening in some way. The remaining accidents involved leaving the <br />roadway along 10 or accidents occurring at the driveway entrances. <br /> <br />An aerial view of this median opening is attached to this case. At the present time all turning <br />movements are permitted at his location except for u turns from eastbound to west bound 10. <br />However westbound to eastbound u turns are permitted. <br /> <br />Increasing roadway safety often corresponds with limiting driver options. At intersections this <br />translates into eliminating potential conflicts by decreasing the turning movement available to <br />the motorist. Consequently this would reduce access to commercial properties which is highly <br />desired by those establishments. Below are several alternatives which could be considered to <br />increase the safety of this intersection. These alternatives are listed in order of greatest to least <br />impact on adjacent businesses. <br /> <br />1. Closure of the median - This would be the greatest improvement in safety at this <br />location. If in place over the accident period 12 of the 18 accidents would have been <br />prevented. It also has the greatest access impact on access to the businesses on both sides <br />of the highway at this location. <br /> <br />2. Install a pork chop island at the entrance into the Licensing Bureau - Accidents 1, 3, 6, <br />13,15, and 16 involved vehicle access to the Licensing Bureau drive entrance. The pork <br />chop would allow only right in! right out turning movements from the Licensing Bureau <br />as well as prevent left turning movements from eastbound Highway 10 into this drive. <br /> <br />3. Restrict eastbound to west bound u turns ~ although this would eliminate a potential <br />conflict no accidents have been attributed to this movement. <br /> <br />4. Reduce the width of the median opening and reorient its location - The length of this <br />median opening atthis location is approximately 70 feet in length compared to 45 feet at <br />Tungsten Street; 55 feet at Feldspar Street; 45 feet at Traprock Street; and 45 feet at <br />Bowers Drive. The narrower median opening restricts turning traffic to more rigidly <br /> <br />19 <br />
