CARNATION - Following a three-week closure, repairs on the Tolt Hill Bridge were expected to begin last week with reopening planned for Sept. 9, according to the King County Department of Transportation.
Spokesperson Rochelle Ogershok said the bridge was closed Aug. 3 after an inspection revealed severe deterioration (caused by corrosion) to the steel beams supporting the structure. Following closure, she said, additional analysis and ultrasonic testing showed the presence of significant corrosion at additional locations.
"Once that was discovered, the engineers decided the bridge needed to be closed until it could be worked on," she said. "Based on the analysis, engineers began designing the repairs, which include additional steel beam reinforcement just below both railings of the bridge."
Ogershok said work was scheduled to start the beginning of the week of Aug. 27, but that was dependent on the delivery of the steel, adding that crews will be working extended hours if necessary to complete the work by Sunday, Sept. 9, for the Monday morning commute.
Detour routes are SR 202 through Fall City, SR 203 and W. Snoqualmie Valley Road.
"Bridges in King County undergo rigorous inspections every couple of years," Ogershok said. "Bridges in the Snoqualmie Valley are subject to flooding and subsequent corrosion so the engineers need to be on the lookout for that sort of thing."
