add N2_N (the road to Jaflong is N2)
add Z2012
add Z2011
add N210
add R248
move R280 west to the next major intersection
add N205_E (where OSM's trunks split just south of R280)
N208
add N205_W
add Z2013 (the first road to the south, just west of N205_W)

move Mad north to the center of town

move ChoChaRd just barely east to Z2031 (the very next road south)
R360
add Z2032 (the road east of the building marked Shantiniketan on OSM)
add Z2041
add Z2042
R211 -> R211/310
add R210

add R111
add Z1102
add Z1101
N1/N8 -> R110_W
R810 -> N532
Bas -> BasRiv and move west to the underpass (where the road crosses on the almost perfectly east-west portion)
add N802
add Abd
add Z5069 (first intersection north of the shaping point) - or not because it only accesses the frontage road?
(the next few routes - Z8005, Z8203, Z8003 - only access the frontage roads, and I don't see any slip ramps)
R820 -> R820/Z8004
(R821 has no main lane access)
move R812 north to the circle (if that's what's still there)
delete MawaKarFry; there's now a bridge
add Can
add R863
(Z8013 only has frontage road access)
add Z8014 (or is it only frontage road access now?)
Shi -> R862 (but it may have only frontage road access)
add PulBaz
(Z7108 only has frontage road access)
N8/N804

West of here, the route is all wrong, since it uses the new Madhumati Bridge. So delete N803 thru N7/N702_S and replace with:
Z8067
Z8021
Z7004
Z8023
Z7001
N805_S
Z7507
Z7503
Z7505
Z7502
R720
Z7030
Z7504
Z7501
N707_E
N708
N702/707
N7_S

N7/N706 -> N7_N
add Z7551
add R765
add N711_E
move Ben west to N711_W

BGD AH2

see AH1 east of N8

The log claims 20 km between the split with AH1 and the south end of N3 (just south of MatRd). The route we have is 14.5 km, but I have no way of knowing if it's correct or not. So I won't really review the portion thru Dhaka, since it's more likely than not the wrong route.

R747 -> N713/R747
Z7405
add Z7458
Z7404
N78/N704 -> N704/N712 and move north

The AH log only lists N704 to N7 at Jhenaidah. But N704 now ends at N703, which is old N7. So we could send AH41 along 704-703-7. But given that N7 was realigned to the east side of the bypass, I think it makes the most sense to take AH41 down the east side as well. And that is the way signed to Jashore.

The AH log doesn't list N709, but given the ferry on N7 it makes sense.

KUETRd

R760
add Z7606
N7/N709_S -> N7_KhuW
R770 -> N805
MadRd -> Foy?

It seems that N7 has been cut back to Digraj, about 6 km north of the ferry. In particular, it's precisely at the former railroad crossing. So do we cut back AH41 to here or continue it to the ferry?

I've just found that in 2015 AH41 was amended to bypass Dhaka. Everything between N105 and N105_W (west of N3/N4) gets deleted and replaced with the following:

N1/R113 (instead of N105)
R114
N2
PurExpy
Z3010
Z3003
R301
Z3008_S
Z3008_N
N3
N4_S (instead of N105_W)
