Expect these updates to arch the bridge in the coming months
Before the West Linn-Oregon City arch bridge can be restored to its original grandeur, some demolition has to occur. Here is what the contractor plans to work on in the coming weeks:
n Main Street bridge approach: At the Oregon City end of the bridge, people may have recently seen or heard the removal of the worn out, concrete bridge approach (roadway). After the rebar is replaced, the new concrete approach will be poured, resulting in a smoother transition for motorists from Main Street onto the bridge.
n Sidewalks: The old sidewalk and bridge railings are being removed between Main Street and McLoughlin Boulevard (OR 99E). Before the bridge closure, the deterioration of railings was quite visible. The first step in replacement of the sidewalks and railings involves concrete cutting and jack hammering. In January, the new sidewalks will begin to be formed and poured. To do this work, the alleys on both sides of the bridge in Oregon City have been temporarily closed. They will remain closed for several months.
n Steel repair, Gunite removal and Shotcrete application: Steel repair work continues throughout the bridge and preparations are under way for the application of Shotcrete on sections of steel that are in good condition or have been repaired. This work is weather dependent.
On the Oregon City side, the Shotcrete replacement is complete under the bridge from the river to the road deck.
In mid-December, the barges were be removed from the Oregon City side for the winter. The barges on the West Linn side will remain until the river starts its usual winter rise. Most of the hydrodemolition work has ended until spring. It will then start up again to remove the Gunite (old concrete) from the upper arches.
n Holiday shutdown: The bridge project contractor, Wildish Standard Paving, will be off work until Jan. 3.
n Noise: Over the next several months, project noise on the Oregon City side will be at a high level due to rivet replacement, concrete cutting, jack hammering and breaking up the debris.
The Oregon Department of Transportation (ODOT) is working with a noise consultant to take steps to monitor and reduce the noise effect. In January, concrete cutting on the railings and sidewalks will begin on the West Linn side.
n January work: In early January, the contractor will prepare and install the Shotcrete under the bridge deck on the West Linn side. In addition, steel repair continues on the arches and under the bridge.
n Bridge shuttle news: ODOT is trying to determine if there is sufficient need to offer bridge shuttle service later in the evenings on Saturdays and Sundays between 8 and 11 p.m. There are also budgetary considerations.
The daily ridership for the bridge shuttle continues to be high. After 45 weeks of service, the total number of shuttle riders is 30,941 including 5,425 bicyclists.
Later weekday evening service was added in September on a trial basis and will be evaluated at the end of January to see if it will continue.
The average number of pedestrians riding each weekday is currently 113 and the daily average of bicyclists is 18.
