It looks like the 1988 bridge used steel girders.
 |
| HistoricBridges The 1938 bridge was a Scherzer Rolling lift type. In 1988, the superstructure was replaced. |
The 1938 bridge had plenty of rivets. The 1988 bridge has none.

BRIDGE MILESTONE:First concrete beams set for Lafayette Bridge in Bay City
Steve Pajak: Is this an ironworker crew setting these into place?
Marty Brawley: Steve Pajak Carpenters set those.
Gary Beckert: Steve Pajak Ain't a hope in hell of a iron worker touching concrete.

They evidently set all six beams in one day. All of the underwater work is done.

| 2:11 video @ 0:13 Lafayette Bridge project reaches major milestone as first concrete beams are set The project began in Dec 2024, and they are on schedule to open in June 2027. Each beam is 60 tons and about 125' (38m) long. They do an "in-air transfer" with the two cranes to set the beams. |
 |
| ConstructionEquipmentGuide, MDOT The cost is up to $113.6m. |
 |
| ConstructionEquipmentGuide, MDOT "There were two American 9299 cranes that were used to assist with the project." |
I went to Ray Roacha's Facebook page and found a video of a beam lift. The lift starts at 5:07 while he is focused on a hose they wound up earlier in the video. As expected, as the crane slews the beam toward the river, the truck backs up the trailer under the other end of the beam. At 14:05, both cranes are hooked up to the beam as part of the transfer. 14:46 the yellow crane has the beam because the red crane dropped its hook so that the riggers can remove it from that end of the beam. 16:15 the red crane is free of the beam and the hook is headed to the other end. 17:36 they are connected the red crane to the other end. 19:17 after he changed the battery, the riggers were removing the beam from the trailer. 20:31 both cranes are now moving the beam into position. 22:30 those are big piles of counterweights on the mobile (red) crane. 23:52 I don't see anybody signalling the yellow crane operator. Are they using radios? I have not been able to understand the chatter that is on the video. 26:02 I don't know what the drone operator was looking for, but he is back to the beam here. 26:31 now I see a handsignal. The last few inches always takes a long time. 27:34 is measuring how close the beam is to the abutment. 29:12 is the beam down while the drone was looking at houses? 29:25 yes, I see the rigging wiggling a little bit. 29:47 and the rigging is slack on the other end as well. 33:52 why didn't the haul the trailers away while the beam was being set so that the area is clear for the next beam? In fact, I expected the next beam to already be backed into position. 34:14 the answer is that they need the red crane to put the back trailer on top of the front trailer so that one truck can haul both trailers. And we can clearly see that the mobile crane has 8 axles. (The biggest I've seen is 9.) Unfortunately, he decides to look at beam pads instead of the trailer lift. 38:05 finally, we are back to the trailer lift, but we don't stay there.
