In the Spotlight
The WMTMC tracked two snow storms in the first two weeks of December 2009, which resulted in several
incidents on the Grand Rapids area freeways. WMTMC Control Room Operators coordinated with state and local
law enforcement officials, as well as local media, to help reduce the impact of these weather events on area
freeways.
Twenty-seven incidents caused lane or freeway closures during December 2009, similar to December 2008 but
greater than the previous 12-month average of approximately 19 lane, ramp, and freeway closures.
A large number of incidents (50) occurred on US-131 in December 2009. In comparison, there were approximately
25 incidents in November 2009, December 2008, and the previous 12-month average.
Construction of the new WMTMC Control Room continued in December, with the painting, carpeting, and
cabinetry now complete. In the coming months, the wiring for the ITS equipment and video wall will be
installed. It's exciting to see the new space taking shape.
