EUGENE, Ore. — Nighttime closures of HWY 58 at the Salt Creek Tunnel will end Thursday, October 11. Motorist can still expect one lane of travel, controlled by flaggers and a pilot car, as daytime construction will continue, but shouldn’t expect more than a 20 minute delay.
Phase 1 construction on the tunnel will continue until snow is in the forecast, at which construction will end and both lanes of travel will open. During phase 1 the tunnel floor was lowered and repaved, a new drainage system was developed and half of the foundation piles were placed for the half viaducts.
Phase 2 of the tunnel’s construction will start again next spring and nighttime closures will resume. Crews plan on replacing the remaining foundation piles for the half viaducts, construct the half viaducts, repair and seal the tunnel liner, repair the tunnel lighting, construct two Variable Message Signs and a weather station.
In the end, the two phase, $9.6 million project will have repaired and modernized the Salt Creek Tunnel, built in 1939. The primary contractor for the project is Capital Concrete Construction of Oregon.
