It is not my intention to leave anyone out of your entire group but I am extending my special thanks and accolades to your site supervisor, Will Stover, in particular. Being a manager and details type person I thought it was important to let you know that this type of service does not go unnoticed.
I realize this was a relatively small project for your firm and did not expect the level of professionalism and attention to detail it received. Now that the work is complete in Oakland, I wanted to take a moment and let you know how pleased we, the owner and engineers were with the work that was performed by your team at Oakland on the recent anchor project. MD&B used rubber tire blasting mats for containment purposes on the project that ultimately displaced 13,000 cubic yards of rock. Trail 1 at Middle Falls and Upper Falls to Genesee Arch Bridge Closed until April of 2023 Trail 6/6A (Lower Falls Foot Bridge Trail) closed until April of 2023. After each blast, the construction crew lowered an excavator, filled the bucket, hoisted the material out and cleared the lift for further use by MD&B's crew. MD&B drilled and installed rock anchors at every level to maintain stability of the rock face. Outcomeĭue to both the project limits and the environmental concerns, MD&B could not blast each 90-foot rock cut at once, and therefore had to take the ledge cut down in six 15-foot lifts. The frequency of blasting was also limited due to a nearby eagle's nest. It was critical that no rock from the blast contaminate the river, 50 to 100 feet below. Environmental concerns also came into play during this project. Challengesĭue to the blast locations, the work area could only be accessed via cranes, which lowered the drill and workers to the worksite in man baskets. American Bridge Company, the general contractor, subcontracted with MD&B to blast and stabilize the pockets for the foundations. The foundations of the arch are set back into the canyon walls. The river runs through a canyon that is over 200 feet deep at this location. Finished in 1931, the ornate concrete arch bridge faced with white granite sees about 75,000 vehicles.
The new bridge features a 483-foot steel arch over the Genesee River. The beautiful Veterans Memorial Bridge carries Route 104 over the Genesee gorge in Rochester. The existing bridge remained in service during the construction of the new bridge. The new 963-foot bridge is on a parallel alignment 75 feet south of the current bridge. The weight and speed of trains operating over the bridge are restricted to ensure safe operation.
The current bridge was built in 1875 and strengthened in 19. Geotechnical Drilling & Foundation ServicesĪ major transportation railroad bridge over the Genesee River needed to be replaced to increase efficiency on that route.
