Speed limit here, northbound or eastbound, is still 60 mph.

The speed limit here is only 55 mph, not 60 as "maxspeed" parameter seems to suggest. This is due to construction on the roads that has been going on for three years at least.

Speed limit heading west: 65 mph.

Speed limit here has been dropped to 55 mph (westbound), although it previously jumped to 65 at this point.

This is yet another location on 40 westbound where the navigation service thinks that I need to take an exit and then come immediately back onto the highway, rather than simply continuing on the highway itself.

Once again, the OsmAnd navigator service is trying to make me exit the highway and then go right back onto it rather than simply continuing in a straight line (westbound). This suggests to me that something is wrong with the Open Street Map data.

Speed limit here is 65mph

The speed limit here needs to be corrected to 70 per hour.

Speed limit is still 65 miles per hour here
