ID: ID 46 south of I-84

[US 89]

TM shows SH 46 with a south end at I-84 exit 157. Since 2010, this has not been the case, and 46 now continues south to end at US 30 just southeast of Buhl.

If this was left out in the past due to being unsigned, that is no longer the case. Signage is not amazing by any means, but there are straight arrows heading south at the I-84 interchange...



...and if you keep going south, after that first bend to the west, there is in fact a reassurance marker:

There are also "St Hwy 46" markers on the signal posts at the intersection of ID46 and US30 in Buhl.  Because it is signed at both ends of the 2010 extension, I think ID46 should be updated to reflect the Buhl extension.

Anecdotal evidence - The Idaho state highway map also shows ID46 extending south to Buhl.
