Oregon City Bridge
The State Highway Department has been requested by the County Court of Clackamas County to prepare plans and estimates for a bridge over the Willamette River at Oregon City. This will replace the old suspension bridge at that place which is too light for the modern traffic conditions in that vicinity.
Surveys and studies of the site are being conducted at this time. In this case, as is customary, the State Highway Department will furnish plans free of cost to the County.
