Here is LADOTD's web page on I-49 North:
http://www.dotd.la.gov/administration/public_info/projects/i49north/There is also a link to a map of the project on that page, most recently updated as of June 29.
The only Segments which have had final paving, signing, etc. contracts let are Segment A and Segment B.
The rest of the "Completion Dates" on the page are for the initial grubbing, etc. contracts.
Segment C's grubbing work is supposed to be finished by the end of this month.
Segment A is supposed to be completed next month.
Segment B currently on track to be completed in March, 2011.
Segment E's grubbing contract will be let on September 29.
Segment F's grubbing contract tentatively scheduled for October.
Segment G's grubbing contract tentatively scheduled for October.
Segment C's final paving, signing, etc. contract has not yet been tentatively scheduled as through Feb., 2011.
Grubbing work for Segments H and I should have started by now.
No motorists will be allowed on A & B before 2013. Provides a great opportunity for "up close" inspection of Segment A and, possibly by time of meet, Segment B.
Road Scholar may be amenable to bottle rocket wars and/or hot-rodding on Segment A.

EDIT - ADDITIONAL THOUGHT
IIRC AHTD has 2 separate current grubbing, etc. projects underway from current end of AR 549 to LA state line. I think dividing line for 2 projects is Co. Road 2, with the section closest to AR 549 having been let first. By time of meet, you should have some pretty good viewing opportunities.
