April 2012

Week of April 23:
Crews continue to work on the bridge decking and railings, which may include periodic lane closures on SW Hood and Macadam during the day and some nights. Crews will direct traffic as needed.

In addition to the bridge work, crews will pave the SW Gibbs/SW Kelly Street intersection at the west end of the bridge. Due to the high traffic volumes at the intersection, work will take place between 9:00 am and 3:00 pm. Flaggers will direct motorists around the work zone.

April 10
Over the next two weeks (April 9 - 13 and April 16 - 20) there will be nighttime work. Crews will be patching and painting the new concrete barrier along Hood Avenue (between the Ross Island Bridge and SW Curry Street). Weather permitting, crews will also pressure wash and seal the concrete bridge deck, working their way from the west side of the bridge (Lair Hill) to the east side (South Waterfront). Nearby neighbors should expect nighttime noise from trucks, generators for lights, and equipment.

Roadway closures are expected to change each night. The contractor will be closing lanes of SW Hood Avenue, northbound and southbound I-5, northbound and southbound I-405, and SW Macadam Avenue that are below or near the work area. Motorists should follow signed detour routes.

In addition to the nighttime work, daytime crews will begin constructing the new median island in the SW Gibbs/SW Kelly Street intersection at the west end of the bridge. The median island will provide a refuge for pedestrians so they can cross the street one half at a time. Due to the high traffic volumes at the intersection, work will take place between 9:00 am and 3:00 pm. Flaggers will direct motorists around the work zone.

March 2012

March 30
Crews will begin work to secure the new concrete barrier along SW Hood Avenue March 30. Nearby neighbors should expect nighttime noise between 8:00 pm and 5:00 am while this work takes place. The contractor will have measures in place to minimize the noise from jackhammers and drills and there will also be noise from trucks, generators for lights and equipment.

Work on the barrier will continue into next week. Crews are expected to continue to secure the barrier on Monday night, April 2 between 8:00 pm and 5:00 am. Starting Tuesday night and continuing through the rest of the week, crews will continue working nights to paint and finish the barrier.

The contractor will close SW Hood Avenue and southbound I-5 exit 299A between 8:00 pm and 5:00 am to complete this work. Signed detours will direct motorists around the work zone.

The contractor made good progress this week on the bridge. Nighttime crews finished removing the temporary overhang forms and brackets on the bridge over SW Hood Avenue, I-5 and SW Macadam Ave. The railing and fence on the bridge is nearly complete and new sidewalk was poured along SW Hood Avenue.

March 23
Over the next two weeks (March 26 - 30 and April 2 - 6) there will be nighttime work. Working their way from the west side of the bridge (Lair Hill) to the east side (South Waterfront), crews will remove temporary overhang forms and brackets on the bridge that were used to place the concrete deck. The work is expected to take at least one week and could continue into the following week. Crews will also secure the new concrete barrier to the roadway pavement on SW Hood Avenue between the Ross Island Bridge and SW Curry Street.

Nearby neighbors should expect nighttime noise as crews use drills to place pins in the barrier, as well as noise from trucks, generators for lights, and equipment.

Roadway closures are expected to change each night. The contractor will be closing lanes of SW Hood Avenue, northbound and southbound I-5, northbound and southbound I-405, and SW Macadam Avenue that are below or near the area of work. Motorists should follow signed detour routes.

March 15
Friday 3/16 and Monday 3/19 crews will work on pouring a new curb and sidewalk along Hood Avenue. This work may close one lane of traffic, so please watch for traffic flaggers (between 9 am and 3 pm). Work on the bridge railing continues, along with installation of the elevator and stair work.

Traffic Updates: Friday (3/16) and Monday (3/19), crews will be working along Hood Avenue and may close one lane for this work. Watch for traffic flaggers during the day (9 am to 3 pm).

March 1
Over the next two weeks (March 5-9 and March 12-16) there will be nighttime work. Crews will remove temporary rock fill between Hood Avenue and I-5 South to restore the bank to its pre-construction condition, as well as install new concrete barrier along Hood Avenue between the Ross Island Bridge and SW Curry Street. Neighbors should expect nighttime noise as crews excavate the temporary rock fill and haul it away.

I-5 South Exit 299A (Oregon 43/Hwy 26/Ross Island Bridge/Macadam Ave) will be closed Monday through Friday nights after 8:00 pm while this work takes place. Southbound I-5 traffic will be detoured toward the Morrison Bridge and can follow the I-5 South/Hwy 43 Detour signs via SW Naito Parkway, US 26 Ross Island Bridge, SW Kelly Street, SW Curry Street and SW Hood Avenue. Motorists should look for the I-5 South/Highway 43 South detour signs and exit the freeway approximately 1.5 miles north of the closed exit.

Crews have been making progress with pouring the concrete bridge deck and are beginning to install the ornamental bridge railing. The elevator is also being installed this week.

February 2012

February 24
On February 27th (depending on weather) the next segment of bridge deck will be poured. A concrete pump truck will be parked on the shoulder of Hood Ramp, near Gibbs Street. Traffic may be slowed periodically for truck entry.

February 16
Thursday and Friday nights (2/16 and 2/17) most of the I-5, I-405 lanes (north and southbound) will be closed (see below). Signs will show the detour route for traffic. Friday night lane closures will be staggered to minimize disruption to traffic. All lanes will re-open by 5:00 am the following morning.

This work will allow workers to install protective fabric on the bridge for the concrete pouring and to tighten bolts on the bridge spans.

Thursday night (2/16) starting at 10:30 pm, crews will begin to close all lanes on I-5 and I-405 in the northbound direction and one lane I-405 in the southbound direction. Signs will show the detour route for traffic (same detours as previous closures).

Friday night (2/17) the Hood Avenue Ramp will begin closure at 8:00 pm, then all lanes of I-5 southbound will be closed starting at 10:30 pm. These lane closures will be staggered to minimize disruption to traffic. All lanes will re-open by 5:00 am the following morning.

February 9
The first section of concrete pouring, for the west side bridge deck, is planned to start at 9:00 am Friday, February 10. Pouring concrete will not take place if there is too much rain; pushing back the pouring until Monday or Tuesday (2/13 or 2/14).

Gibbs Street will be closed except for local access during this concrete pour. Please check web page for future lane closures and restrictions needed for the concrete pouring. January 2012

Weekend of January 20
Work continues on the west landing plaza, as well as on the elevator and stairs on the east landing. Work will also continue on the bridge structure to prepare for the concrete pouring, which is expected to take place in February.

No work is scheduled for the weekend of January 21-22.

Update: January 12
Thursday night (January 12) crews will work on placing the final bridge span and placing the deck forming and temporary hand railing, so that crews will be able to pour the concrete deck in early February.

SW Macadam Avenue north of SW Curry Street and the nearby I-5 northbound on-ramp will be CLOSED between 8:00 p.m. and 5:00 a.m. Traffic detours are listed below. Also, the southbound lane of I-5 will be closed Thursday and potentially Friday (1/13) nights beginning at 10:00 p.m. until 5:00 a.m. the next morning.

Week of January 9: Final Bridge Span Placements Scheduled
Workers are preparing to place the final bridge spans across SW Macadam Avenue and connect to the bridge’s elevator tower. Roadway closures and detours are planned as part of this work.

On Monday (January 9) a large crane will be set up next to SW Macadam Avenue near the Tram tower, closing the sidewalk on SW Macadam Avenue that connects SW Curry Street to SW Kelly Avenue. The sidewalk closure will be in effect Monday, January 9 at 8:00 a.m. through Friday, January 13 at 7:00 a.m.

Starting Tuesday night (January 10) crews will work for three nights to place the final bridge spans. On each of these three nights (January 10, 11, and 12) SW Macadam Avenue north of SW Curry Street and the nearby I-5 northbound on-ramp will be CLOSED between 8:00 p.m. and 5:00 a.m. Traffic detours are listed below.

Nearby residents in Lair Hill and South Waterfront may experience nighttime noise as the crews bolt the bridge spans together. However, this work will be further way from residences than previous bridge span placements, which should lessen the direct noise and vibrations.

Detour Routes:
Between Tuesday night, January 10 from 8:00 p.m. to Friday morning, January 13 at 5:00 a.m. the detour routes below will be in affect.

SW Macadam Avenue northbound will be closed at SW Curry Street. This will affect motorists traveling northbound on SW Macadam Avenue, as well as motorists leaving I-5 North at Exit 299A (Oregon 43/Hwy 26/Ross Island Bridge/Macadam Ave).
