A cable-stayed suspension bridge or CSS bridge merges the designs of cable-stayed bridges and suspension bridges. The suspension bridge's architecture is better at handling the load in the middle of the bridge, while the cable stayed bridge is better suited to handle the load closest to the tower. Combining these two architectural engineering ideas into a hybrid has been done in Istanbul with the Yavuz Sultan Selim Bridge, and in New York City with the Brooklyn Bridge.{{cite web | title=Brooklyn Bridge – History, Construction, & Facts | website=Encyclopædia Britannica | url=https://www.britannica.com/topic/Brooklyn-Bridge | access-date=January 24, 2020 | archive-date=June 5, 2023 | archive-url=https://web.archive.org/web/20230605114111/https://www.britannica.com/topic/Brooklyn-Bridge | url-status=live }} A bridge over the Krishna River in India has been approved in October 2022 that will be a CSS bridge design.{{cite journal|title=A Study on Cable-Stayed Bridges|journal=Applied Mechanics and Materials |volume=193-194|issue=|date=August 2012|author=Bahareh Bannazadeh|pages=193–194|doi=10.4028/www.scientific.net/AMM.193-194.1113|bibcode=2012AMM...193.1113B |s2cid=108446116 |display-authors=et. al.}}{{cite journal | doi=10.1088/1757-899X/1070/1/012039 | title=Analysis of a long span cable-stayed suspension hybrid bridge considering variable intermediate side span supports | year=2021 | last1=Savaliya | first1=G.
