You need to edit your question to be more specific about what arch and what tunnel.
I presume the tunnel has an arch shaped cross-section with a semicircle on top of a rectangle. In this case the volume of the tunnel is the volume of the cuboid bottom plus the volume of half cylinder which forms the top. The volume of the half cylindrical top is ½πr²h = ½ × π × (6m)² × 25m = 450π m³ The volume of the cuboid is length × width × height. The length is 25m. The width is the diameter of the top half cylinder which is twice the radius at 2 x 6m = 12 m. The height is not clear. I am going to presume it is to the top of the arch, so that the height of the cuboid is the height less the radius of the cylinder, namely 7m - 6m = 1m. Thus the volume of the cuboid bit is 25m x 12m x 1m = 300 m³ Thus the volume of the tunnel as a whole is 300 m³ + 450π m³ ≈ 1713.72 m³ (If the 7m height refers to the height of the vertical walls, then the volume of the cuboid is 25m x 12m x 7m = 2100 m³ and the volume of the tunnel is 2100 m³ + 450π m³ ≈ 3513.72 m³.)
The website runningwarehouse.com offers a shoe finder where you can select the arch height depending on your footprint. What you can do is dampen the bottom of your foot then step on a blank piece of paper and ompare your imprint with the arch height options to determine your arch height. Click on search and the brands that have styles with your arch height will be displayed. Asics, Brooks and Saucony make high arch running shoes.

An extended arch is called a vault. Most tunnel are built using vaults. It's a bunch of arches put together.

The Longfellow Bridge has a height of about 70 feet (21 meters) from the surface of the water to the apex of the arch at its highest point.
