Overnight Extension of I-5 Southbound Closure to Marquam Bridge Nights of Sept 21-23

Purpose: ODOT is taking advantage of the I-5 southbound closure to complete required 2-year maintenance inspections on the Marquam Bridge. During these closures, crews will use an Under Bridge Inspection Truck to identify safety concerns and document the condition of the bridge's structural elements for maintenance needs. 

Why Now?  By scheduling this work alongside I-5 southbound closures for the Rose Quarter project, ODOT is able to share resources, reduce cost, and avoid the separate closures that these inspections would otherwise require.
