** Includes cost of standard wing walls and bridge barrier. For special construction review unit cost with MCDOT bridge section.*** 16 m box with approval only. Generally a non-section line, low volume location.

Cost in Red is based on bridges constructed from 2005-2008 as there was not any new data available for FY 2010
