The answers to this are in the existing GMB project study documents. There are breakdowns by origin and destination, in both a.m. and p.m. peaks.
Surprise: 2/3 of the traffic going through the tunnel is headed to Richmond for daytime purposes (work/shop/etc).
Surprise: 1/3 of the traffic is going directly to/from the Steveston part of Richmond, an area that would not be well-served by a crossing located anywhere else.

Your question is backwards, based on the studies we have in hand. The bridge/tunnel's main purpose is all about getting people to Richmond for employment purposes. Serving Delta or Vancouver traffic is a secondary concern of this crossing.

The tunnel is nearly as old as the Patullo, and was built using a questionable design which will not age as well as the Patullo. It can be argued that the tunnel is even less safe than the Patullo.

This is not really the issue at hand. The issue at hand is that there is major employment in Richmond, and the tunnel gets people there for that purpose. 60% of the tunnel traffic is due to this need. This is not at odds with the regional growth strategy.

Because the Port Mann Bridge is not pointing in the right direction. The employment served by the GMT is mainly in Richmond and south Vancouver.

The documents we have in-hand also address this question. There is not enough density in Delta to justify this, and as Clayton pointed out, we don't want there to be enough density there. And if we only built a rapid transit crossing, we would be left with a tunnel that is basically a second Patullo in terms of its long-term reliability.
