The bell tolls for tollbooths
Article Abstract:
Electronic-toll-collection (ETC) facilities are the newest traffic engineering solution due to the increased congestion on highways and at tollbooths. The toll-road industries have already incorporated ETC technology although some older plazas are facing problems in their change of construction. Older toll plazas will need to integrate ETC facilities at great expense or add a dedicated lane for ETC travel. However, these solutions are problematized by the traditional response to congestion through increasing the number of lanes.

Toll plaza to stand on buried columns
Article Abstract:
The expansion of the Blue Water Bridge toll plaza in Port Huron, MI, involved the installation of compacted stone columns to control structural settlement and prevent shear failure in soft ground underlying the current construction. Engineers installed the compacted-stone columns by using a hydraulically powered bottom feed vibrator. The columns can support higher loads than the surrounding soil and provides lateral and vertical support and drainage. The $42.3 million project began in Aug 1991 and is set to finish in Nov 1995.
