Pedestrian bridges in Cupertino; a double arch bridge supported at the median might be US$5M?

Those seem highly misleading...the tunnel is extremely lavish...brickwork all around. The bridge on the other hand, appears to be spanning a small 2 lane road, without needing massive approach ramps.
We already know that building a bridge in the region over 7/8 costs at least 7 million, and that's likely with much smaller approach ramps due to the superelevation of the road.
