Required information The length of the river span of a bridge is $1962.5 \mathrm{ft}$. The total length of the bridge is $6680 \mathrm{ft}$. Convert the length of the river span of the bridge to meters. $\times 10$ $\mathrm{m}$

Step 1 ：Given the length of the river span of a bridge is 1962.5 ft and the total length of the bridge is 6680 ft.

Step 2 ：We need to convert the length of the river span of the bridge from feet to meters.

Step 3 ：To convert the length from feet to meters, we can use the conversion factor 1 foot = 0.3048 meters.

Step 4 ：We multiply the length of the river span of the bridge in feet by this conversion factor to get the length in meters: \(1962.5 \times 0.3048 = 598.1700000000001\) meters.

Step 5 ：Final Answer: The length of the river span of the bridge in meters is approximately \(\boxed{598.17}\).
