As far as my knowledge works, it's 180m.

120m is the length of the river.
Quarter from left means 1/4x120=30
Quarter from right means 1/4x120=30
So: 120+30+30=180

Do let me know if Iam wrong.

Stay blesses
It is possible to clear if we get exact statement again..If quarter of total length is mentioned then answer will be 240,if quarter of bridge in air is mentioned then answer will be 180 m..
