You still had "MAINE" on I-95 North in Portsmouth. March 6, 2019.


Gad!  What an excessively oversized structre.

Well they DO warn about crosswinds as you go up to that wonderful bridge in the background. :-P

Back on Thursday, 21 May, I was able to drive down I-93 south from the I-293 split in Manchester to the Massachusetts state line. Here is what I saw on that day since my last drive down that corridor was back in December 2019:

1. NHDOT is slowly starting to replace the variable speed limit signs with static ones along the I-93 corridor, as they reach the end of their service life. From a previous NHDOT job shadow back on 25 July 2019, I was told that the TMC in Concord didn't really have any practical uses for it, some of the signs were "unreliable" and "kept having issues", and one time during a heavy snowstorm, they could not change the speed limit to 45 mph (72 km/h)*, as the inclement weather was causing signal issues between devices. I don't have a picture of it, but one of the speed limit signs replaced was on 93 south before the 293 split (before, after). As of Oct 2019, that segment now has a permanent speed limit of 55 mph (89 km/h), and a minimum speed limit of 45 mph (72 km/h). It is also worth noticing that the speed limit from ~MM18.4 to ~MM14.2 is still 55 mph (89 km/h) for some reason and not 65 mph (105 km/h) like it used to be...

2. The "RIGHT LANE ENDS 1000 FT" banner on the I-93 pull-through sign at the 293 split needs to be removed. At least going southbound, it is now three continuous lanes through the I-293 interchange.



3. I-93 (southbound) now has four continuous lanes from ~MM18.4 to ~MM14.2 (though Exit 5, NH 28/N. Londonderry), for a length of ~4.2 miles (6.8 km). I don't know if signage for the I-293 split were updated heading northbound, or if travel lanes were opened on the northbound direction, as I have yet to check that.


4. The widened freeway after ~MM14.2 narrows down to two travel lanes through Exit 4 (NH 102, Derry/Londonderry). Southbound traffic through the Exit 4 work zone shifts over to the northbound carriageway. Work continues on the I-93 mainline and Exit 4 ramps in this area. The southbound carriageway can be seen on the right hand side of the images.


5. I-93 reverts back to three lanes at MM10.4 after the Exit 4 southbound on-ramp merges with the mainline. From MM7.6 onwards to the Mass. State Line, they are doing median work as well as some activity near the NH/MA border. Not sure what it is, but that sound wall looks new.


Does anyone know when four continuous travel lanes from Massachusetts to ~MM10.4-14.2 (Exit 4 area) will be fully open to traffic? Last time I heard, salt runoff issues prevented them from opening all four travel lanes, limiting them to three in each direction. I wonder if that is what the median work is all about.

*Also, does anyone know what happens to those variable speed signs during inclement weather (i.e., snowstorm)? Do they say a reduced speed on the SPEED LIMIT portion, with the MINIMUM blanked out, or is the sign blanked out completely during these events? Also, have those signs been reduced (or increased) in times that are NOT inclement weather or a work zone area (i.e. traffic congestion)?

Southbound is definitely still 55, but northbound the portable variable signs do sometimes display 65 north of exit 5.

Northbound now opens up a mile or two before the split, but no signage was updated. Still just has the temporary ground mounted orange signs.

I've never seen them display anything other than the normal speed limit. Snow, traffic congestion, a major crash, still the normal speed limit. NHDOT does reduce the limit during snowstorms, but I've never seen the signs reflect the lower limit (unlike in Maine).

According to the project website, rebuildingi93.com, 93 should be done with 4 lanes by fall 2020. The exit 4 contract as well as the south of exit 1 widening should be complete in the fall and the final contract for this megaproject (also to be completed in the fall) is constructing a 4th lane from exit 1 to exit 5 (which will probably involve mostly restriping the lanes). Not sure if this is the most up to date info, but thats what the project page states.

That is contract 14633J out in the works right now, which is widening the median strip to accommodate a fourth lane from Exit 1 to Exit 3 (approximately 4.8 miles (7.7 km) southbound and 6.1 miles (9.8 km) northbound) along with some ITS work from exit 1 to exit 5 which is expected to last from spring to fall 2020. Like I said earlier, I believe this is being done because a long time ago, NHDOT could only design and open the road to three lanes of traffic from exit 1 to 3 because of salt runoff issues.

I just drove the Spaulding Turnpike today and noticed something a bit strange today while they were doing some roadworks. While driving between exits 4 and 6 northbound, I noticed that NHDOT posted a new permanent static speed limit sign that says:

SPEED LIMIT 55
MINIMUM 40

Interesting enough, it is not very far from an existing SPEED LIMIT 55 sign. This is the first time I have ever seen NHDOT post a minimum speed of 40 mph (65 km/h) ever... wonder why that is the case?

Typically, in a 65 MPH zone, the minimum is 45.  Most Speed Limit 65 signs throughout NH add the minimum.

However, in a quick check on street view, I failed to see a Speed Limit 55 sign posting a minimum (outside of the electronic ones on I-93 south of Manchester).  So in that regard, perhaps when the max speed limit is 55, the minimum is 40.  We're just now seeing this posted.  Perhaps?
