Speedway growth

Marathon Petroleum boats are a familiar sight on the Ohio River. One of them is named the Speedway, which also is a Marathon operation that is growing substantially, as this article explains. Most of the growth is outside the Ohio Valley, but still, growth is growth.

Another problem at Locks and Dam 52

This came out yesterday, and for some reason my email provider sent it to the spam box, so I didn't see it until today.

There's another problem at Locks and Dam 52. From a navigation notice:

The primary (1200’) lock chamber at Locks and Dam 52 will be closed for 48 hours between Saturday August 25th and Tuesday August 28th. Marietta Repair Station will be performing repairs to the lower miter gate. Inflows coming into the project site will dictate whether or not the auxiliary chamber is open or closed due to out draft conditions.

I wonder if the Corps of  Engineers will lay off half its repair fleet when the old dam goes out of service permanently here in a few weeks, if all goes according to schedule.
