The Mackinac Bridge opened in 1957. Beyond the important job of connecting the upper and lower peninsulas of our state, it’s also pretty cool looking.

The steel grating that is the road deck of much of the bridge has been replaced.

Because of that, seven pieces of the original steel grating from the 1950s that weigh two tons each are now up for auction.

The prices as of this writing range in price from $195-$465. Here are more specifics from the listing.

Pieces are approximately 5 1/2 feet X 38 feet and 5 inches deep. Condition is used with corrosion and section loss appropriate to steel that is 60 years old. Each piece weighs about 2 tons.

Grating was originally coated with lead based paint. Much of this is gone, but Buyer will have to sign a “Hold Harmless agreement” related to the lead paint and the structural condition of the grating. The Hold Harmless agreement is an attachment to the auction ad.

Seller agrees to cut the grating section into two shorter pieces for ease of shipping if desired. Price of this one cut is included in the bid. No other cutting or manipulation of the grating will be done by the seller.

Seller will load the grating for transport but is not responsible for securing, etc.
