Both bridges have the same design, and they were "recognized as 1934 "Most Beautiful Steel Bridge" in Class A by the American Institute of Steel Construction (AISC)." [both BridgeHunters] Both bridges have a main span of 616' and were rehabilitated in 1981.

I learned of the Bourne Bridge because of this photo of the Cape Cod Canal RR Bridge.

The Sagamore doesn't need approach trusses like the Bourne because it is built between two hills.

You can tell that Cape Code was a tourist area because both BridgeHunter pages have several postcard images.

A five-year Massachusetts study concludes that both bridges should be replaced for about $1b. It would replace today's 48' wide 4-lane bridges with 138' wide 6-lane bridges and restructure the roads at the ends of the bridges. The USACE, which would fund the replacement of the bridges themselves, is still studying replacement vs. major refurbishment. [May 2019: CapeNews] On Apr 3, 2020 the USACE decided to replace the bridges. [MDOT-background]
