Title: Puerto Rico statehood and its effects on roads
Post by: mgk920 on November 07, 2012, 04:41:34 PM
Among all of the other flotsam on Tuesday, 2012-11-05, voters in Puerto Rico decided to seek statehood in the USA.  The margin was 61% for full statehood, 33% for a revised territorial status and about 6% for independence.

Interesting.

are PR1 to PR4 all full freeways, or are they in the interstate system the same way that the Alaska ones are?

Alaska-style, but there's a lot more freeway than in Alaska (almost all toll).

Puerto Rico has only three paper Interstates, PRI-1 through PRI-3.  Last I drove them, ten years ago, PRI-2 and PRI-3 had some stretches of non-freeway divided highway.  Most of the freeway segments are tolled.

Since there no longer is much of a Federal funding advantage to Interstate designation (there was back in 1980, when Alaska's senator Ted Stevens pushed through the Interstate designations for both Alaska and Puerto Rico), there might not be a lot of interest in seeking new designations.

My understanding is that the PR Interstates actually never got transferred off the original surface routes as the freeways (mostly toll roads) were built. I-PR2 is the one particular case where I know this to have happened. I think Oscar Voss's website goes into that. Of course, I'd expect that if they were ever to be signed, the designations would be transferred.

Either a) Oscar (I think it was him) is accurate, b) FHWA is accurate, or c) Oscar WAS accurate but the FHWA figured out they needed to transfer designations. I'd like to believe c).

I see the original surface road along the north shore.

That map shows PRI-2 following the current PR-22 autopista (toll road) bypassing the old PR-2 surface road, to Arecibo where PRI-2 continues to Ponce via Mayaguez where PR-2 apparently hasn't yet been replaced by an autopista.  (I don't know what progress if any has been made on extending the PR-22 autopista west of Arecibo, since I haven't been there for a decade and I don't know enough Spanish to comfortably navigate the Puerto Rico DTOP website.)  And it also shows PRI-3 following the PR 53 autopista, as well as other highways like PR-3 and PR-26 not yet bypassed/replaced by an autopista. 

In the 50 states, don't Interstate designations more or less automatically move from an old alignment to an upgraded new one, without having to get AASHTO approval for every shift?  For example, did CalTrans need such approval to move I-15 near the Miramar air station north of San Diego, from the old alignment that is now Kearney Villa Road to the new routing to the east?

Will statehood require Puerto Rico to follow the MUTCD more closely? Currently, a lot of PR's signs seem to resemble the MUTCD, translated to Spanish, but I believe I remember seeing some somewhat significant differences. Conversely, what are the odds of the MUTCD being revised to accommodate PR's unique situations, namely, the addition of options for Spanish or bilingual signage?

Currently the route shield situation in PR is a mess...primary, secondary, and tertiary PR routes exist, with some switching back and forth between systems at random; an urban variant of the primary shield exists for seemingly no reason, the secondary shield looks like a CR marker, while the tertiary marker looks like the default MUTCD circle for state highways. I doubt being a state would do much to change this, but it really needs to be cleaned up somehow.

I have heard that PR - were it to become a state - would be asked to be bilingual.  At the present time, there's a lot of English here and there, but the vast majority of Puerto Ricans are not proficient in English.  If (and it's a big if) PR attains statehood, I'd imagine that bilingual signage would be gradually phased in.   

BTW, the statehood vote comes with a great big asterisk.  The way in which the ballot was organized was a problem, with one question of "are you happy" about the present status (yes or no) and the second part was "if not, then which of 3 options would you choose".   Many left part one blank, some voted yes on part 1, then voted in part 2, others voted vice-versa.  Also, the pro-statehood governor of PR (a Republican) lost a close election to a status-quo candidate (aligned with the D's).  So, that hurts advocacy for statehood in Washington. 

Basically, it's complicated and won't happen as soon as the headlines may imply.

I think bilingual signage would be the way to go.   I personally have no problem with Puerto Rico having Spanish as the de facto primary language, though I think English should be at least offered to all students in its public schools.

So most of the signs should be in Spanish and English, with the possible exception of STOP signs, which should just read STOP.

Yeah, I read that - seems the voters in P.R. sent a contradictory message to the rest of the United States.

Though I think that they would be better-off as a U.S. state overall, as compared to continuing with the current "commonwealth" status. 

And since U.S. citizens from Puerto Rico have been killed and injured in wars fighting for the United States for most of the 20th (and 21st) centuries, it seems very appropriate that they become a state.

I'm all for adding Puerto Rico as a 51st state, since they have been a commonwealth for all those years. And as for the signs, I'd prefer a bilingual set, meaning the signs would be in both English and Spanish.

On the surface, you'd think that this would be a no-brainer.  But that's not so.  Because, like most things in life, it's complicated.  Although what you've written is true, there is the other side of the issue to be considered.  For example, residents of Puerto Rico do not have to pay U.S. Federal Income Tax.  They pay tax to the government of the Commonwealth of Puerto Rico.  So, the money stays right there.  As far as money goes, they're a net winner as far as government funding is concern.

In fact, the island has been given certain tax breaks and advantages by the U.S. Government.  For some industries (for example, pharmaceuticals), it is essentially a Duty-Free zone.  That's been successful at creating good-paying jobs.   So, there are multiple issues to be considered on each side of the issue.  Not the least of which is the fact that Puerto Ricans are a cohesive ethnic group - a "culture", a "people".   Of U.S. states only Hawaiians feel that way and they're not nearly as unanimous in percentage as las boricuas.  Can you imagine someone telling you that they're half Italian and half Ohioan?  No. 

So there is a cultural concern to be considered as well.  There are many reasons why the commonwealth status has remained popular and in place for so long.  For the plurality of Puerto Ricans, it has represented the best of both worlds.  And, they'll always be Puerto Rican first and American second - they know this. 

It's not quite so cut-and-dried.  But I am in favor of the Puerto Rican people making that decision for themselves before doing anything.

English should be **REQUIRED** to be taught in Puerto Rican schools whether it becomes a state or not.  English should be taught from kindergarten all the way to 12th grade, and in colleges.  Americans need to be proficient in English just for practicality's sake.

I'm thinking Puerto Rico will continue to have its own state MUTCD, except it will be asked to be brought into substantial conformance - meaning the same sign dimensions, symbols, and phraseology. The language of the phraseology will be different, but I bet FHWA will allow that within the realm of "substantial" in the interest of not causing accidents.

However, the US (and consequently Puerto Rico) is not a signatory to the Vienna Convention.  STOP signs in the Americas tend to use the native language i.e. ARRET, ALTO, etc.

Absolutely correct!  Spanish-speaking islands in the Caribbean and almost all of South America (except Guyana, Suriname and French Guiana) use "PARE".  Mexico and Central America use "ALTO".   

If Puerto Rico were to become a state (an interesting prospect), I suppose it's possible that they would be forced to transition to bilingual or even English STOP signs.  Federal highway funding is usually tied to the maintenance of standards.  But, an exception could be permitted too. 

Hard to guess on this one.

I have friends from PR.  English is a required subject at least where they went to school.  I would imagine its like French being required in Canada... not too many in Alberta are proficient in French.

Biggest issue relative to road is not what it says on a stop sign.

PR uses the metric system for distance signs, and sells gasoline in metric.  But imports US standard cars with "English" measurements.  And thus posts "English" speed limit signs.   With no notice on the signage that this is the case.  So you would see "San Juan 50" and are just supposed to know that that is 50 km, and then US style but in Spanish  "55" signs are are just supposed to know that that means miles.

Not at all.  There is nothing I know of in the MUTCD that says a state must use the Imperial/English system or the Metric/French system of measurement on its highways.

I believe the MUTCD explicitly allows either or both and has a design for a metric speed limit sign that has the number enclosed in a black circle with "km/h" underneath. An older edition prescribed a standard-looking speed limit sign with a yellow plaque above reading "METRIC" and a white plaque below reading "km/h," but presumably they came to their senses and realized the potential for trouble if the supplemental plaques were blown away in a storm or stolen by pranksters.
