Blomberg Bridge Project

In 2017, Blomberg Bridge was widened from 6' to 8' and new 4x6 decking was installed.

 

A special thanks to Gail & David Nelson and Paul Gabriel who spent 2 days to complete this project, Scot Bromann who secured the steel and provided the welder/generator for the project, and the Rib Lake Ski & Snowshoe Club for support and funding.

 

Before the project - 6' wide:

The ramp leading up to the bridge was not changed.  In this picture, the steel trestles are "inside" the ramp.

 

 

 

Old Decking Removed:

 

 

 

Widening the Bridge:

Nine angle iron cross members were cut to "separate" the trestles.  Then a weld at each end of the trestle that connected it to the support beams was cut. 

 

At the far end of the bridge David is pounding the trestle with sledge hammer to move it out.  Paul is in the Bobcat with a boom connected to the top of the trestle to keep it upright.  The bucket of the orange tractor is supporting the trestle so it cannot tip "out".  There is wood blocking supporting the cut angle iron so the trestle cannot tip "in".  We also clamped steel around 2 of the cut angle irons to keep the 2 halves of the bridge aligned.

 

At first the trestle would not move.  We found one of the cross members was not cut completely thru.  After cutting that cross member, the trestle moved out very easily.

 

 

 

8' Wide:

The ramp leading up to the bridge was not changed.  In this picture, the steel trestles are now "outside" of the ramp.
