3M has expanded from 28,000 sf to 56,000 sf in Building No. 10 at the park. Park owner Crown West Realty LLC's in-house Margie McHugill negotiated the transaction.

Part of 3M's Traffic Control Materials Division, 3M Dynamic Messaging plans to begin producing two new "active school-zone signs" next month. One is a sign that gives motorists passing through a school zone the speed limit that is being enforced in the zone at that time. The other is a driver-feedback speed sign that tells motorists how fast they're going and activates flashing warning lights when they're exceeding the posted speed by more than 5 mph.

3M says it also will begin production of some larger versions of the sign for highway and freeway use. They include variable "time-to-destination" signs for use in areas with heavy traffic congestion, and priority-control road signs that can forewarn motorists of approaching emergency vehicles.
