The replacement of the Sellwood Bridge is about to reach a major milestone. Over a 12-hour period next month, the old bridge deck will be slid about 60 feet north onto some temporary supports in the river.
The roadway on either end will then be reattached, so drivers can still use the old bridge. Then, workers can start in earnest to build the new bridge. Commuters will drive alongside the new one as it takes shape. The completion date is in 2016.
