I-93 Signage, South of Boston Update

Image
By
Had a chance this past weekend to drive the southern end of I-93 from Braintree to Canton and back. With the opening of the new fourth lane northbound between I-95 and MA 24 on Wednesday (11/14), this portion of the '128-Add-a-Lane' project is almost complete. (For a list of upcoming opening dates for '128 South' between MA 109 and MA 24, see this blog post, a response to a question I had after taking this road trip). The signage along this stretch of I-93 has now, with an exception or two, been completely replaced.

1. New signage southbound from MA 24 to I-95
Two of the final signs to go in southbound have been the advance overhead signs for Exit 3, Houghton's Pond. Signs 1/2 mile before the exit have been placed both on the MA 24 on-ramp and here, along I-93:
One of the signs not updated yet is the 1 mile advance sign, which may not be the responsibility of this project. After the MA 24 ramp merge they have added a pair of I-93/US 1 reassurance markers on each side of the highway. Here's the assembly along the right side:
The only other new sign on I-93 South since my last trip was an 'End I-93' sign after the MA 138 exit, I spotted it too late to get a photo this time. Though technically a sign for I-95, they have also put in a new center posted overhead for Exit 13 just before the merge with I-95 North:
 This replaced two separate signs for the exit that were placed on the bridge above both the mainline and the off-ramp, you may also notice a new 'Begin MA 128' sign assembly. Guess they didn't have any MA state Begin banners, or, as some people suggest, they are preparing for Interstate 128.

2. New signage northbound
The final signs northbound appear to be in place (with the possible exception of another Exit 2 assembly at the on-ramp from I-95 North). Here's a look at the new Exit signage and a new 'Begin I-93' assembly:
The covered sign was an indicator on whether the breakdown lane was open for travel. I assume it will be removed after the new 4th lane opens this week. There is still some remaining construction at the I-95 on-ramp:
The concrete barriers are for continued construction of a 5th travel lane from I-95 to MA 138. This may, or may not open at the same time as the 4th lane. The first North I-93/US 1 reassurance marker is currently also being protected behind the barrier:
The last two new overhead signs in this direction have to do with current Exit 4, MA 24:
These new signs forgo a diagrammatic display or arrows for text, the left 3 lanes currently restricted to two. There's also a new separate auxiliary surface sign after the Exit 3 on-ramp that lists MA 24 also goes to Brockton and New Bedford. The final new signage at the off-ramp is a little different:
 Here the arrows return. The roadway between the MA 24 on and off-ramps will soon be the only 3-lane stretch of  '128' south of I-93 in Reading.

3. Notes on the I-93 Signage Project, Randolph to Boston
There has been continued slow progress on this contract. The latest MassDOT listing says the project is now 7% complete as of the end of October. There are new Series 'E' aka blue signage for services running from before the MA 28 exit northbound to MA 37. A couple of these, however, were already replaced before the original contract was stopped in 2009 and re-advertised. I did not notice any new 'green' signage, either on the mainline or at the interchanges. Hopefully, 2013 will see more rapid progress on sign replacement, both along the '128' stretch and the Southeast Expressway.

Crescent City Connection (New Orleans, LA)

By
The Crescent City Connection is a massive dual-span steel truss bridge that spans the lower Mississippi River at downtown New Orleans, about 95 river miles upstream from the mouth of the great river at the Head of Passes Light. If counted as a single bi-directional highway bridge, the parallel spans combine to form the single busiest bridge on the Mississippi River and its importance as a linchpin in the region’s transportation network cannot be overstated. While there have been various schemes over the years to construct bridges downriver from Algiers Point, this bridge has been the southernmost bridge on the Mississippi River since its initial construction in the 1950s. The years immediately following the end of World War II were a transformational period in the history of New Orleans. Already one of the great economic and cultural centers of the American Deep South, it was recognized at this time that major changes and improvements to the city’s transportation infrastructure would b...

Old US Route 99 through Tipton, Tulare, and Tagus Ranch

By
This summer I had a look into the alignment history of US Route 99 through the Tulare County communities of Tipton, Tulare, and Tagus Ranch.  While this slab below might seem like much it is one of the few remaining reminders of how US Route 99 was during the 1920s in Tulare County. This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below. Gribblenation US Route 99 Page Part 1; the history of US Route 99 in Tipton, Tulare, and Tagus Ranch Tipton and Tulare were both founded in 1872 as sidings of the Southern Pacific Railroad.  The Southern Pacific Railroad laid the groundwork for development of southern San Joaquin Valley.  Previous to the Southern Pacific Railroad travel via wagon or foot in Central California tended to avoid San Joaquin Valley in favor of the Stockton-Los Angeles Road.  The Stockton Los Ange...

Former US Route 101 and California State Route 41 through Paso Robles

By
Paso Robles is a city located on the Salinas River of San Luis Obispo County, California.  As originally configured the surface alignments of US Route 101 and California State Route 41 converged in downtown Paso Robles.  US Route 101 originally was aligned through Paso Robles via Spring Street.  California State Route 41 entered the City of Paso Robles via Union Road and 13th Street where it intersected US Route 101 at Spring Street.  US Route 101 and California State Route 41 departed Paso Robles southbound via a multiplex which split near Templeton.   Pictured above is the cover of the September/October 1957 California Highways & Public Works which features construction of the Paso Robles Bypass.  Pictured below is the 1935 Division of Highways Map of San Luis Obispo County which depicts US Route 101 and California State Route 41 intersecting in downtown Paso Robles.   Part 1; the history of US Route 101 and California State Route 41 i...
