Project Category: Bridge Replacement, Road Construction


Description:

The Cougar Creek Bridge was a 26' timber span sitting on mortared rock abutments built in 1926 that had outrun its service life. Conway Construction replaced the existing bridge with a new 60' span that allowed for a wider roadway. In addition, the creek channel wasreturned to a natural state not possible with the narrow existing structure. In order to do this, CCC had to divert the Cougar Creek through a bypass during an in water work period. CCC also replaced the roadway approaches and installed drainage which included over 300 yards of rock excavation.

Project Category: Bridge Rehabilitation


Description:

The iconic Good Pasture Covered Bridge is the most photographed of its kind in Oregon. Conway Construction Company took on this challenging rehabilitation project which required temporary support of the structure via two 140' tubular steel trusses installed inside the bridge. CCC installed new truss splice plates, tuned and post-tensioned the trusses, replaced the timber deck and stringers, replaced the portal siding and replaced the bridge rail. CCC's sub-contractors painted the bridge and installed LED lighting to the exterior. With the exception of four single night closures, all of the work was done while under live traffic. The project was a success ensuring that the Good Pasture Bridge will remain an inspiration to photographers for years to come.

Usk Bridge: Major Maintenance


Owner: WSDOT/Pend Orielle County

Location: Usk, WA

Project Size:$1,100,000

Category: Bridge Rehabilitation, Bridge Overlay


Description:


At 2,281 feet long the Usk Bridge spans the Pend Orielle River one hour North of Spokane, WA. The length of the bridge coupled with the requirement to maintain one lane of traffic during construction posed significant logistical challenges. Conway Construction completed the work of hydrodemolition of the bridge deck, silica fume overlay, bridge joint replacement, damaged concrete repairs, wood pile splice and wood pile FRP wraps within the time allotted for completion. CCC performed the many silica fume placements at night to satisfy traffic restraints and environmental conditions. CCC performed the hydrodemolition next to live traffic, protecting the traveling public for flying debris. CCC processed over one million gallons of contaminated water resulting from the hydrodemolition of the bridge deck.

Throughout construction the Morrison Bridge was kept open to both car and truck traffic on the bridge and watercraft beneath it. Car and truck traffic was accommodated by a plan that reduced traffic to two lanes directed to the north half of the bridge during stage 1 and to the south half during stage 2. Stage 1 temporary traffic control included the installation of a temporary thrie-beam rail and a truck-mounted impact attenuator. Both served to protect the work area from adjacent traffic. Stage 2 temporary traffic control included a combination of thrie-beam rail, four truck-mounted impact attenuators, and concrete traffic barrier.  Concurrently, at any given time one span remained inoperable while the other remained operable. CCC was on-call 24 hours a day, 7 days a week to accommodate any maritime traffic requests for a bridge opening. For each opening CCC vacated the deck of the operable span and moved the truck-mounted attenuator. The thrie-beam rail “rode” with the operable span. Once the vessel passed and the deck was lowered and CCC replaced the attenuator and resumed work. During high water conditions CCC furnished an auxiliary tug boat to help guide vessels through the narrowed opening created by the lifting of a single span.  The original bridge deck was comprised of 5” deep open steel decking  that was welded to W 16 x 36 steel stringers. These stringers are 3’-10” on-center and rest upon, or are coped into, transverse floor beams up to6’-10 1/2”deep. CCC’s task was to remove all the steel grating and two-thirds of the stringers, replace the stringers with new steel beams of the same size and replace the decking with the FRP decking. Special care was taken due to lead paint coating all the existing steel.  The stringers of the 50+ year-old structure were originally connected to the floor beams with rivets. This posed a particular challenge for CCC. The age of the structure and the nature of riveting caused the location of existing holes in the floor beams to vary from one stringer to the next. CCC concluded that it would be best to field-drill the vast majority of holes in the new stringers, holes through which ¾” bolts are being placed to fasten them to the existing floor beams.  The FRP was simple and straightforward to work with. The full-time oversight of the system’s inventor provided further assurances. After the new stringers were installed CCC installed the FRP base panels. In order to ease bolting, CCC then drilled through both the FRP and the steel stringers. Once the two were bolted together, sheets of FRP were placed on the base panel and the two were fastened with over 60,000 screws. This top panel was roughened and coated with polymer. A fiberglass fabric face sheet was rolled onto the tacky, polymer coated surface and another layer of polymer was placed upon it. After drying, this polymer surface was roughened before a mineral impregnated polymer finish surface was installed.
