February 8, 2019 Supporting Act

Despite the weather, work continues at the Sharon Valley Road Bridge in Sharon Township. This week has been all about building additional supports for the beams that were placed in January. The contractor has been working on the concrete forms of the midspan diaphragms, supports built between the beams. We are hoping to pour the concrete for these diaphragms sometime next week if the weather cooperates.

After the diaphragms have been set, the bridge deck pouring can begin.

If you have any questions, please contact Aaron Berkholz, project manager, at (734) 327-6648 or berkholza@wcroads.org.

January 25, 2019 Beam are set!

All seven of the beams are now in their final resting position! Now the contractor’s crew is working on setting forms for the concrete “diaphragms” between the bridge beams.

Bridge crews will not be working next week due to the forecasted snow and cold temperatures. They plan on returning to work on Monday, February 4th.

If you have any questions, please contact Aaron Berkholz, project manager, at (734) 327-6648 or berkholza@wcroads.org.

Setting of the Beams on Sharon Valley Road Bridge

January 14, 2019 It’s (Almost) Beam Time!

This milder winter is certainly helping us out this season. We’ve been making steady progress, the west concrete abutment is in place and sand backfill was placed on Friday. Large stones aka riprap will likely be placed tomorrow.

The west steel sheet cofferdam will remain in place, as a measure to avoid any further disturbance of the underlying artesian condition. The crew will soon begin the process of cutting off and removing the top portion of the steel sheets (seen in the photo below).

Next up will be the concrete work for the west wingwalls and back wall, and placing the concrete beams across the river. Once these items are in place, and if the weather cooperates, the concrete deck will be poured. After the deck has been successfully poured, the project will pause until the spring.

Thanks for your patience on this project. If you have any questions, please contact Aaron Berkholz, project manager, at (734) 327-6648 or berkholza@wcroads.org.

Sharon Valley Road Bridge Construction – Photo taken January 11, 2019

December 27, 2018 Moving Water

We continue to make slow progress on the Sharon Valley Road Bridge reconstruction.

Last week, we de-watered the cofferdam and the artesian flows inside the cofferdam have been significantly reduced. Our contractor has now started prep work for the abutment/wingwalls. The reinforcing steel crew is expected to be onsite this week. Hopefully, we will be in a position to pour concrete the week after New Year’s, if the weather cooperates – pouring concrete diaphragms and a deck in freezing temperatures over open water is very challenging.

If you have any questions about this project, please contact Aaron Berkholz, project manager, at (734) 327-6648 or berkholza@wcroads.org.

Making Progress on the Sharon Valley Road Bridge cofferdam.

December 6, 2018 Slow but Sure

We are slowly making progress on addressing the artesian condition discovered earlier this Fall. In November, Spartan Specialties, our specialty subcontractor, successfully installed a “piezometer” well, allowing us to monitor the artesian flow.

The contractor also installed two well points just outside of the steel cofferdam enclosure in the northwest corner. We plan to use these pumps to direct the water away from our work.

You may have noticed that this effort required the construction of a temporary access road along the north side of the project. The temporary access will be removed once we complete the artesian-related work.

Unfortunately, this type of work is slow. Please know that we are working as hard as we can to remedy this difficult situation.

If you have any questions about this project, please contact Aaron Berkholz, project manager, at (734) 327-6648 or berkholza@wcroads.org.

October 25, 2018 We Have a Plan

We do have a plan but we won’t be able to complete the bridge replacement before winter.

In mid-September, we discovered an artesian condition that temporarily halted our construction. After much work, we now have devised an artesian remediation plan and our contractor has engaged specialty subcontractors to conduct the related work. We are expecting these contractors to begin working sometime in November. We cannot move forward with any other part of the bridge reconstruction until this has been addressed.

Considering typical timelines for the bridge work, and the limitations presented by winter weather conditions, completing the bridge and the road approach work will extend into the spring. Our hope is to get as much work as we can before winter and then come back in the spring. The bridge and road will remain closed until spring.

We know this is disappointing news. If you have any questions about this project, please contact Aaron Berkholz, the new project manager for this project. Aaron can be reached at (734) 327-6648 or berkholza@wcroads.org.

P.S. The maintenance work on the Austin Road bridge in Bridgewater Township should be completed this week, as long as the weather cooperates.

September 19, 2018 Well, Well, Well…We’ve found an Artesian

Unfortunately this week we have hit a snag in the replacement of the Sharon Valley Road bridge. While our contractor was constructing the west abutment (base where the bridge will connect), they discovered an unexpected artesian, a pressurized underground water pocket.

We are currently evaluating all the options to minimize the impacts of the artesian flow but this means that the project is now behind schedule. We are hoping to resume construction soon.

If you have any questions, please contact Kelly Jones, project manager, jonesk@wcroads.org or (734) 327-6647.

Sharon Valley Road Bridge September 17, 2018

The east abutment has been completed but we have hit a snag on the west abutment.

August 14, 2018 Sharon Valley Road Bridge Update

Our contractor is making great progress on the Sharon Valley Road Bridge!

The cofferdam (steel sheet enclosure) has been fully installed for both bridge abutments (foundations), the piles (steel pipes needed as part of the abutment support) have also been installed. The concrete pad has been poured for the east abutment and the next step will be to install the piles and concrete pad for the west abutment. Once that has been completed, we will start constructing both abutment walls.

Overall, we are on schedule. Thanks for your patience!

July 18, 2018 Out With the Old & In With the New

As you can see, the Sharon Valley Rd Bridge replacement project is well underway.  The majority of the old bridge has been removed and our contractor, E.T. MacKenzie Company, continues to install the cofferdam (steel sheet enclosure) around the work area to aid in building the new foundations.

Please remember the road is closed to all traffic for the duration of the project and it is strongly recommended for all motorists to follow the posted detour route.  Thank you for your patience during this temporary inconvenience.

Please contact Kelly Jones at jonesk@wcroads.org or visit the project webpage at https://www.wcroads.org/wcrc-project/sharon-valley-road-bridge/ if you have any questions.

The old bridge has been removed!

It’s take some large equipment to replace a bridge
