Reassurance shield as I-15 Business begins. This is an odd business loop because it extends past I-15 to connect to I-40. This segment between I-40 and I-15 is actually in the books as a spur of SR 40, but it is not signed as such anywhere, so we’ll log it here as I-15 Business. This serves as the connection between I-40 west and I-15 north, which does not have a direct ramp.
