Speed The posted speed along County Road 116 is 55 miles per hour (mph) with the exception of the area between CSAH 83 (Armstrong Boulevard) and CSAH 57 (Sunfish Lake Boulevard), and between CSAH 57 and TH 47 where the posted speed is 50 mph. In addition to the above -posted speeds, there are three areas where speed advisory signs are posted near horizontal curves. • Just east of CSAH 83 (Armstrong Boulevard)(50 mph advisory speed) • Between Tungsten and Krypton Streets (40 mph advisory speed) • Between Tower Pond Drive and TH 47 (40 mph advisory speed) As part of documenting the existing conditions, SRF collected actual vehicle speeds to compare them to posted speeds. The intent of this data collection was to identify capacity and operations issues that may not show up in daily volume number or in the intersection analyses. The speed data was collected in November 2001 at the three locations. The information is presented in Table 4.

The information collected west of Magnesium Street is in a 40 mph speed advisory area, due to sharp horizontal curves. While speeds through this location are lower than the 50 mph posted speed limit, they are above the speed advisory for this segment of the road. SRF Consulting Group, Inc. - 10 - February 2004
