I agree with Nathan's comment; however, considering the razor-thin escape from the wrecking ball that this bridge pulled off, I'm sure happy to see carriage bolts on this historic bridge over a new, ugly, MOB, which was the plan until only a couple of years ago!
Overall this is both a good and amazing outcome for a bridge of this size. The use of bolts is a disappointment being as it is something that multiple organizations reached out to them in favor of. They could have done the rivets if they had wanted to.
I went out with my family today and took photos of the newly restored bridge. Overall good restoration; most of the rivets along the bottom chords of the bridge have been replaced with bolts and the bearings have been replaced. Other than that, mainly blast and paint, and new concrete deck.
As part of the Long Meadow Bridge, the previous and NOT original wooden deck was replaced with a "lightweight" reinforced concrete deck with no wear layer. The ORIGINAL deck was 1920 era reinforced concrete with an asphalt wear layer. The original deck was failing and replaced with the wooden deck some time in the late 1940s to early 1950s.
The contractors used modern "lightweight" reinforced concrete without a wear layer to provide long life, reduce the dead weight of the bridge, and retain most of the design capacity of the bridge. They also used that material because the ORIGINAL deck was reinforce concrete, and not wood. Since this was a NRHP Bridge Restoration, they also used pine boards for forms rather than modern steel forms to get the "board texture" that would have been present on the curbing of the original deck.
Great to see... Especially for one that once appeared to be a goner!
Outstanding!! After a 14-year wait, it will be nice to have public access to this bridge once again! The pipe-and-cable railings appear to be similar to those used on the Gateway Trail Bridge over Manning Avenue in Washington County--minimal visual intrusion to the truss portions of the bridge should allow for easy viewing. I will be sure to make it a point to visit once I'm in the area again.
The Long Meadow Bridge restoration is complete. The bridge is now open to pedestrian and bicyclist traffic. The bridge is scheduled to close during the Spring of 2017 to allow unhindered access to lightweight paving equipment, which will be paving the path between the south end of the Long Meadow Bridge and the north end of the pedestrian/bicyclist portion of the Cedar Avenue Bridge.

Rehab is commencing. The lot near the bridge was closed and this was near as I could get to take this pic.
Plans should be finished and the bid letting commence on this bridge in early 2015 from my talks with the city engineer who has had this project on his desk for over 2o years. The span provides a missing link to the extensive trail system and will be a welcome addition when it is back in service. Kudos to Bloomington, State of Minnesota and the legislature for figuring out how to finance this restoration.
As you point out, most of the deterioration is at the deck level of this bridge or below. However, because it is a through truss, most of the historically significant and load-bearing superstructure is above the deck. Yes, substantial repairs to the flooring system and bottom chord will indeed be needed. However the majority of the trusses above the deck remain in good condition.
Uh, I'm stumped at how this bridge can be rehab'd without essentially rebuilding it from the ground up. Most of the deck and lower framwork are rusted so badly you can see daylight through a lot of the beams and the expansion feet are pressed back to the point they're cracking the concrete abutments. It's like the bridge is on the verge of collapsing under its own weight.
I've been wanting to know who got the design / administration for this bridge. I got out to see it the last time I was in Minneapolis.
We'll be there a lot in the next month.
An RFP for the Old Cedar Avenue Bridge has been issued by the City of Bloomington for Design and Construction Administration Services. If there is someone that can take this project on at the design level stage, if there is an engineer out there that would like to work with us on this project I will forward the RFP and move forward to build the team. Standard certs for Minnesota required.
The proposal is due by end of January.
Congrats to the City of Bloomington, MN on voting for restoring the bridge. Thanks to you, the bridge will be restored and reopened to traffic by 2015! http://thebridgehunter.areavoices.com/2013/09/16/long-meadow...
Hats off to the state of MN and City of Bloomington on deciding for restoring the Cedar Ave. Bridge. History and other info can be found here: http://thebridgehunter.areavoices.com/2013/06/28/long-meadow...
I never intended to own bridges in this lifetime, but it is looking like this one may come the Workin' Bridges way. The team of experts is ready.
The engineer sent me the inspection reports and this one is tough. They are meeting next week. Bloomington does not want to own this bridge, any precedent for a toll bike/pedestrian bridge to offset the costs.
It has a lot of section loss and rust, all spans need to be pulled to be restored.
Let's hear some ideas. Workin' Bridges would collaborate with another bridge company on this one to figure this huge project out.
Well something better done with this bridge in the next few years. Cracked abutments, rotting beams, and deck that's shot won't prevent this from falling into Long Meadow Lake anytime soon.
Julie there are some on Flickr
When you break it down it is just 5 spans, each 170' long. We can do this. Will talk to Bloomington Engineer next week but the director of the refuge (federal funding) said that anything would be better than the project stopped because no one could get a handle on the escalating cost. He had already talked with the engineer and they were interested, potentially, in our view point. Workin' Bridges doesn't look at it with the extra 0's, so maybe we can collaborate with another bridge company to get this one done too. Especially in Minnesota, the education of restoration is so important, we could potentially reach a lot of people and train a whole new generation on the skills required to take care of the stuff they will inherit.
It is near a city where it can get a lot of great use. any other pictures out there?
This is the old Cedar Ave. bridge.
Typical MN behavior. A landmark historic bridge screaming for reuse and instead the only thing happening is the owner agency complaining about the bridge. http://www.startribune.com/local/west/124463509.html
