All we get is one extra lane?

Construction has been horrendous on I-40 in Nashville for several years now -- around the I-40/Briley Parkway area. From all appearances it looked like we were going to get 2 extra lanes on each side. Within the past week or so they've finished and opened up the east-bound side. One lane. Basically 4 years of construction and all we get is one new lane? They've added new exit/on ramps at the White Bridge Rd/Charlotte Pike/Briley Parkway intersections ... but it's just moved traffic around a little bit. I haven't noticed any ease in congestion.

One extra lane. Unbelievable! And it's still not even a HOV lane. We have no HOV lanes in West Nashville!! What's the deal? I know some of our south and east Nashville friends say the HOV lanes aren't enforced ... but at least they have them.
