LA: Route Truncations

[cenlaroads]

According to Louisiana DOTD Road Transfer maps and updated GMSV imagery, the following routes have been truncated:

LA 338 has been truncated from LA 14 Business to LA 14, which is concurrent with LA 82 Truck:  Signs removed at the old terminus.  Signs removed south of the new terminus.

LA 577 Spur has been truncated on its east end from the wildlife refuge to this location.

LA 934 has been truncated on its east end to its northern intersection with LA 431, so the concurrency with LA 431 has also been removed.  Signs removed at the south junction with LA 431 and the old east end.  There are also no signs at the new east end indicating any concurrency with LA 431.  I didn't see any signs indicating it even went as far as LA 431, but it is signed at LA 44 on the west.
