Cities that abbreviate "Lane" as "La" on street signs instead of "Ln"

[MATraveler128]

There's several examples of La being used instead of Ln in the Philly suburbs.

For example Guinea Lane in the town of Jamison, PA is abbreviated as Guinea La

I wonder why the MUTCD doesn't have any rules enforcing USPS standard suffixes.

Perhaps part of the reason is that the Postal Service abbreviations are only "recommended." Some of them are rather silly, too, like using "BYU" to mean "Bayou" (an abbreviation that saves essentially no space) and "ISS" for "Islands" (why include the second "S" at all instead of just using "IS" for both singular and plural)?

Some people here might be distressed to learn that the Postal Service defines "BGS" as the recommended abbreviation for "Burgs." (Can't say I've ever heard of a street using "Burg" or "Burgs" as a suffix.)

This includes several common street suffixes (which are only to be used when referencing the name of a roadway): AVE/AV, BLVD, CIR, CT, DR, EXPWY, FRWY/FWY, HWY, PKWY, PL, RD, ST, TER, THWY, TR, TPK, and LN*. All very intuitive, except that "Trail" is abbreviated to "TR" instead of "TRL" (the latter being the USPS preference).

*LN can also be used on changeable message signs to refer to a lane, in context of "center ln", "left ln", etc.

A bit off topic, but I find it interesting that for VMS, the MUTCD abbreviation for "Eastbound" is "E-BND". I've always seen "EB" or "E" for that, and never "E-BND". Same for the other three cardinal directions.
