Project Updates:
New Google aerial imagery shows the completed and opened SR-158 extension from Schillinger Road to Lott Road, it also shows the construction progress around Christmas 2022 on the Glenwood Road bridge and the base+pave to the state line, although the new imagery does not go all the way to the state line. Most of the new SR-158 looks like its been paved except where the Glenwood Road overpass is being built and the tie-in at the state line, where multiple traffic diversions/shifts would be required to completely construct the tie-in to the existing US-98 dual carriageways at the state line. Hopefully by Christmas time this year Mobile will get an early Christmas present in the form of the SR-158 extension opened all the way to the state line.
Aerial imagery in Cullman that was updated shows the SR-157 duplication project coming close to an end, with westbound and eastbound traffic on their own carriageways, 1 lane open each direction. Given the imagery was done in November 2022, the 4-lanes are probably open at this point.
Northeast of Gadsden, the US-411 realignment to complete the 4-lanes to Centre is coming along pretty well. Sentinel hub imagery shows almost all the earthwork completed and the paving around 75-80% complete. I'm expecting US-411 to be moved onto this new alignment by the end of the year, and the old road will become a county/local road, as what happened with the US-411 relocation/dual carriageway project to the south completed a few years ago.
West AL Highway's Linden Bypass south section seems to be well underway (as per Sentinel Hub imagery from March 2023), clearing of the ROW is clearly visible in multiple locations (and I believe it is also beginning in the northern half as well). A bridge culvert being built over Sycamore Creek (near where the bypass meets up with US-43 at the south end) is also clearly visible in that satellite imagery. As for the rest of the project being done in design-build delivery, I am not sure when those parts will break ground, but ROW is being acquired across the entire corridor.
