I-205 Preservation Project Phase 1  between Oregon City and Harold Street in Portland is complete.

 

I-205 Preservation Project Phase 2 between Harold Street in Portland and the Columbia River began construction April 2005. Work on two additional structures south of the main project corridor has been incorporated into this phase for the sake of efficiency.  The project is substantially complete with some signage and striping work continuing into summer 2006.  See the map below of the Phase 2 project area.

 

The central portion of the project runs through the cities of Portland and Maywood Park.

In Phase 1 of the I-205 Preservation Project, the resurfacing of the bridge structures prompted a three to four month closure of two on-ramps to the freeway. The motoring public adapted to the detour routes while the microsilica concrete overlay had time to cure.

 

 

Though work will be conducted during the day on the project, the use of nighttime construction is critical in order to maintain traffic flow on this major interstate freeway.  Currently, the highway functions at capacity. This means there is little room for more traffic. Closing lanes for daytime construction could cause severe traffic congestion.

 

Nighttime construction noise may be audible to residents living along the project corridor. However, noise levels dissipate quickly as distance from the source increases. The paving operation is continually moving. Though construction work may still be audible at 400 feet, its decibel level will be the same as or very similar to existing traffic noise levels.

 

ODOT will keep those nearest the work notified of nighttime, noise-generating activities. A phone number is available for reporting noise problems requiring immediate attention (see below).
