Construction updates for y'all, as of yesterday (4/15/11), cross street by cross street:
LA 1/LA 538: Just clearing so far. They were burning some evergreens in a large heap, which smelled wonderful. Didn't bother going up Albany Rd. because it would just be more of the same.
LA 173: Worth a stop. There's a good amount of active construction here, with one bridge pier in and another slowly taking shape from the ground up. Mainline is graded, ramps are already base-paved for construction vehicle access.
LA 169: Just grading at this point, surprising given the activity just to the south on 173.
US 71: Same thing, just grading here.
Hosston River Rd.: Definitely worth a stop. The I-49 overpass girders are in, but not yet the deck. Pavement is in on either side. Don't walk across, but you can walk up either side and take plenty of photos. It's a nice, remote location if you wanted to get out onto the old alignment, compared to most of the other crossings.
LA 2: Most of the overpass girders are in, but there's still part missing where LA 2 sneaks by. Worth at least a drive-by.
US 71 (take 2): 71 is on the new overpass, and the highway is complete beneath it except for striping. Worth a photo in either direction.
Mira Myrtis Rd.: The new alignment of Mira Myrtis is right next to the existing one and is basically complete starting at US 71. It doesn't look like a twinning, unless the old alignment is going to be completely rebuilt once the new one opens. Certainly possible. I-49 construction is ongoing here, a lot closer to completion than at LA 173 but not to the same degree as Hosston River Rd. (And not only is construction more active, but the road is too - would not recommend stopping here for too long.)
Munnerlyn Chapel Rd.: The road is closed at the new bridge over I-49, but it looks like construction is pretty close to complete.
LA 168, Ida State Line Rd.: Everything's complete at both locations.
Miller CR 2 (Arkansas): There's only grading in at this point, but it looks like construction is about to heat up. I guess because Louisiana is dragging its feet north of Shreveport, Arkansas saw no pressing need to extend AR 549 to the state line - just means that it'll be awhile before any new length of highway opens, even though several miles will be otherwise ready for traffic this year.
