The disturbance that caused yesterday’s activity has pushed on off to the east and left us with the marine clouds, and milder nighttime temperatures, at 9am this morning we were already at 68 degrees. The clouds should at least start to burn back this afternoon but do return tonight, the low near 58.
We continue to watch a large low pressure area off to the west that will push in a weakening front and its associated scattered showers tomorrow where it likely stalls over the area as it continues to weaken and dissipate tomorrow night into Sunday morning. This means we have about a 30% chance of showers tomorrow that diminishes to 20% by Sunday. Daytime highs around 71, nighttime lows near 56.
Labor Day is not looking so bad, partly sunny and 71, the marine clouds do return that night, the low near 54.
The pattern continues into the workweek though the models are still a little mixed. At any rate we hang with partly sunny days, afternoon highs warming a degree or two each day, the marine clouds return each night, lows near 54 still through Thursday.
Clatsop, Tillamook, Washington and Columbia Counties state highway construction update: September 2 –9
6th Through 11th Street: Waterfront Bridges (Astoria) Project (Clatsop County)
This project consists of performing work as follows:
- Install and remove temporary traffic control and pedestrian routes (TPAR)
- Install and remove temporary potable water and sanitary sewer systems
- Perform earthwork
- Install storm sewer systems and water quality structures
- Remove and reconstruct six bridges and trolley crossings (Including tracks)
- Construct roadway, sidewalks and ADA ramps
- Install permanent signs and illumination systems
- Perform additional and incidental work and called for by the Plans and Specifications
This Project replaces six aging bridges at the Astoria Waterfront, at 6th through 11th Streets and to install drainage and water quality facilities at the intersection of Highway 30 and 30th Street in Astoria. Streets will be closed while construction is occurring except for Highway 30. Flaggers will control single lane traffic while construction is occurring at 30th St. The odd numbered streets (7th, 9th and 11th) are scheduled to begin bridge demolition mid-October 2018, and was scheduled to be completed by June 15, 2019. However, due to unforeseeable weather and unanticipated construction issues, construction is expected to be completed by early September, 2019. The remaining work is to be completed no later than June 30, 2020.
Temporary Pedestrian Access Routes (TPAR) will be maintained throughout the work zones and will be ADA compliant.
US 101: Young’s Bay (New Youngs Bay) Bridge Repair Project (Clatsop County)
(Oregon Coast Highway, mileposts 4.53 to 5.33)
This project includes work as follows:
- Install temporary traffic control and;
- replacing rocker bearings;
- repairing the damaged concrete with cathodic protection; and
- replacing compression joint seals.
Initially in mid March, the traveling public will notice the contractor building the containment structure which will be attached to the sides of the bridge, and a barge in the water with support boats bringing crew and materials to and from the barge. Once the containment structure is in place, actual construction will begin. Most of the construction will be performed below the bridge from the barge.
The traveling public can expect periodic single lane closures at night to allow the contractor to move equipment. The lane closures will be Sunday night through Friday morning, 9 p.m. to 5:30 a.m. A complete two week night time closure of the bridge is scheduled in 2021 toward the end of the project.
An alternative route during periods of lane closures and the full night time closure is U.S. 101B over the Old Youngs Bay and Lewis and Clark River Bridges.
OR 22: Sourgrass Creek Culvert Project (MP 11.33)
An existing culvert near milepost 11.33 is being replaced with a new bridge. This new structure is being constructed one half at a time. Due to limited working space one lane of traffic will be closed for the duration of the project. Traffic will be controlled with 24 hour flagging once bridge construction begins.
The South half of the new structure is substantially complete. Traffic is now being routed onto the new structure and work on constructing the North half has begun. One lane will be closed at all times with 24 hour flagging. Expect minor delays. No additional full weekend closures are currently scheduled until early fall of this year. During the closures traffic will be detoured using US 101 and OR 18.
