Washington Avenue Realignment and Tunnel – Tulip City Airport

Holland, Michigan

Mead & Hunt designed a $16 million project that consisted of the realignment of Washington Avenue and construction of an 885-foot cut-and-cover tunnel.  This allows Washington Avenue to travel under a runway and parallel taxiway.  The roadway design consisted of 1.8 miles of reconstruction of rural and urban sections.  Approximately 0.4 mile was designed as a four-lane divided urban freeway.  The rest was designed as a two-lane rural highway.  The urban section used concrete pavement and the rural section used asphalt.  Many municipal utilities were relocated, including water and sanitary sewer.
