Bridge Transformation

While we believe that it is always better to be humble, sometimes you earn the right to ‘toot your horn’ as the saying goes.  This is a story that we are very proud about from a number of perspectives.

A very successful and reputable construction company out of Connecticut – O & G, Inc. – asked us to come and look at a bridge they wanted to replace on the Torrington Golf Club in Goshen, CT.  Torrington is a beautiful golf club with a rich history, including hosting several major regional and national competitions.

The bridge in question was 20’ X 12’ and was used for equipment weighing up to 14,000 lbs.  O & G was donating the bridge to Torrington as a memorial bridge in honor of 3 deceased brothers who were founding partners of O & G and had spent many enjoyable days at Torrington GC.

After supplying an initial quote, we went to examine the old bridge – wood planks on 3 steel beams.  Based on our analysis of the bridge, we determined that the steel beams were in great shape and that we could reduce the cost considerably by incorporating these into the new design.

The original bridge

The particular challenge presented to us was that O & G wanted something very special as a memorial bridge.  Working with our Design Team, O & G decided on a ‘Hogan’ style bridge which has an arched deck and ‘rubble’ stone fascia on each side.  We had to design and engineer a solution that arched the deck, accommodated Vehicular Live Loads of 14,000 lbs. and had a fascia on each side.

The solution started with making structural deck panels with progressively deeper beams to create the arched deck.  We custom fabricated 5 – 4’ panels, each the full width of the bridge, and these were attached to the steel beams to make the ‘structural-arched deck’.

Deck panels being fitted over the steel beams.

From there, we attached the ‘stone’ fascia to the deck beams and capped it with a curb.  The curbs on each side of the bridge deck have inscriptions denoting the memorial tribute that was the inspiration for the bridge.

To anyone looking at this bridge, it appears to have a concrete deck, granite curbs and ‘rubble’ stone with mortar as a structural arch on the sides.  In reality, all of the components added to the steel beams that were retained were made of 100% fiberglass.

We started this story by telling you that our team was particularly proud about this project.  Let us close by telling you why:

  • Our association with the O & G and Torrington GC Teams – a more professional group of people would be hard to find. Their thoroughness and attention to detail made them a pleasure to work with.

  • Our efforts to help our client save money by retaining and re-using steel beams that have another 25+ years of useful life left in them. We credit our Design Team with engineering a method to create an arched deck on flat steel.

  • The final product is really a ‘work of art’ that will serve the members of the Torrington GC for many generations to come and provide a lasting tribute to the 3 deceased brothers who are honored with inscriptions on the bridge.

Links Bridges reaches milestone in Carleton Place!

Links Bridges achieved another milestone this week with the installation of a bridge serving a residential complex.  The bridge connects a parking lot to a building entrance on the 2nd floor of the building at Carleton Place, Ontario residential complex.

The project involved removal of an existing steel bridge which after 25 years of service had severe rust.  The replacement bridge, from Links Bridges Composite Series, was made with FRP (Fiber Reinforced Plastics) beams and decks.  The guard rail was made entirely of HDPE (High Density Poly-ethelene).

This bridge will last for decades.  There are no materials that will rot, rust or require any kind of painting or coatings to maintain the look of the bridge.  The management of the building initially became aware of the Links Bridges alternative from 2 bridges that Links Bridges supplied earlier in 2016 to the nearby community of Smiths Falls, Ontario.

The project was not without its challenges.  To prepare the bridge, the existing bridge details were carefully measured incorporated into the bridge design details.  There was no margin for error.  At each end the bridge had to match existing elevations including at the building entrance where the bridge deck needed to be exactly flush with the door jamb.  There were existing fences, retaining walls and abutments that had to be accommodated if this bridge was going to fit.

The initial plan had been to remove the old bridge and put in the new bridge all in the same day.  Unfortunately, when the old bridge was removed, it was discovered that the existing abutments – which were to be re-used for the new bridge – had suffered some erosion that wasn’t visible until the bridge was removed.

An immediate solution was required because there were residents of the building with access challenges who were reliant on this bridge to come and go.  The Links Bridges’ engineer assessed that the base of the abutments was sound but the integrity of the top surface of the abutments were compromised.

The engineer decided against a ‘concrete’ solution primarily because the temperature was well below freezing levels and not a good situation for concrete to properly cure.  The engineer designed a solution that involved anchoring steel angles to the (uncompromised) side of the abutment.

The Links Bridges team had the required steel fabricated and coated over night.  The next day the team worked in extreme cold conditions to get the abutments ready to receive the bridge.  By mid-afternoon, the bridge was lifted into place.   Everything fit perfectly and by late afternoon, the bridge was fully operational.
