Massachusetts Joins the Mile Post Club

On September 12, 2015 MassDOT posted an advertisement calling for bids on a contract (Project No. 608024) that will convert the state's interstates an other US and State Route expressways to the Geographic Reference Location or Milepost Exit Numbering System starting in 2016. The winning bidder is to be chosen on November 17, 2015. This ends a process started with the 2009 Massachusetts Supplement to the federal MUTCD, section 2E.31 stating: "Massachusetts will be changing all its interchange exit signs statewide to the reference location numbering system, with the entire state highway system to be converted to the new numbers over the next five to ten years." According to a MassDOT source, a chief sign engineer, however, when the state approached the FHWA about funding an ongoing conversion project, they insisted the only way Massachusetts could get 90% federal funding was if they did the project all at once, in what is termed a blanket contract. According to the same source, the project will start in the western part of the state and move east. Short routes like I-84 and I-385 probably being the first to receive the new numbers.

 

When MassDOT committed to the blanket contract for changing the numbers all at once, they already had two projects in the works to update the signage along I-90, the Massachusetts Turnpike, from the NY border to Exit 20 in Allston/Brighton. They decided to change the numbers along I-90 under these two contracts instead. The first project, that will change the numbers from the border east to I-290/I-395 in Auburn was let on August 18. The eastern project is to be advertised on October 31 and will probably be let in December (the remaining signs east of Allston-Brighton date from the extension of I-90 to East Boston in the 1990s and the numbers will be changed under the blanket contract).

 

I was able to get a copy of the signage plans for the western part of I-90 with the new exit numbers. Heading west to east, the first (currently 1) will become 3:


And the final exit under the contract, now 10, will become 90:

 
The most frequently jammed exit, at least westbound, at Sturbridge, now 9, will become 78:

This exit will be the only one to feature diagrammatic signing heading westbound:


US 20, that was formerly on the Exit 9 signage, will be relegated to a ground-level auxiliary sign:

All the I-90 signs on the Turnpike and Ramp will also feature the Mass Pike Logo:


And a Toll Banner at Turnpike Entrances:

For a complete listing of the new exit numbers for the Mass Pike, go to the Future I-90 Mass Pike Exit List. To see more signing plans, go to the I-90 Sign Plans Gallery.

With Massachusetts converting to milepost based numbering, and Connecticut starting to convert with a project currently going on along I-395 (for a gallery of the new signs already put up, visit this Flickr Site). This only leaves three New England states (NH, RI and VT) plus New York (and Interstates in Delaware) as the only remaining consecutive exit number states. With federal mandates calling for a switch, it probably will only be a short time before these states change as well.

In addition to my I-90 list, feel free also to check out my lists covering probable future exit numbers for all of Massachusetts's Interstates and State Route Expressways.

Update:
On November 28, MassDOT placed an advertisement for bidders for the next Mass Pike signing project from Millbury to Boston (Current Exits 10A to 20). The winning bidder is to be announced on February 2, 2016. Work is to start later in the spring.

Hidden California State Route 710 and the Pasadena Gap in the Long Beach Freeway

Infamous and the subject of much controversy the Pasadena Gap in the Long Beach Freeway has long existed as a contentious topic regarding the completion of Interstate 710 and California State Route 710.  While the Pasadena Gap of the Long Beach Freeway effectively has been legislatively blocked the action only came after decades of controversy.  While the Pasadena Gap of the Long Beach Freeway is fairly well known what many don't know is that a small segment was actually constructed south Interstate 210 and the Foothill Freeway.  This disconnected segment of the Long Beach Freeway exists as the unsigned and largely hidden California State Route 710.  On June 29, 2022 the California Transportation Commission relinquished California State Route 710 to the city of Pasadena.  The blog cover above depicts a southward view on the completed Pasadena stub segment of the Long Beach Freeway which ends at California Boulevard.   Part 1; the history of the Pasadena Gap of the Long Beach Freewa

Deer Isle Bridge in Maine

As graceful a bridge that I ever set my eyes upon, the Deer Isle Bridge (officially known as the Deer Isle-Sedgwick Bridge) surprisingly caught my eye as I was driving around coastal Maine one Saturday afternoon. About 35 miles south of Bangor, Maine , the Deer Isle Bridge connects the Blue Hill Peninsula of Downeast Maine with Little Deer Isle over the Eggemoggin Reach on ME 15 between the towns of Sedgwick and Deer Isle . It should be noted that Little Deer Isle is connected to Deer Isle by way of a boulder lined causeway, and there is a storied regatta that takes place on the Eggemoggin Reach each summer. But the Deer Isle Bridge holds many stories, not just for the vacationers who spend part of their summer on Deer Isle or in nearby Stonington , but for the residents throughout the years and the folks who have had a hand bringing this vital link to life.   The Deer Isle Bridge was designed by David Steinman and built by the Phoenix Bridge Company of Phoenixville,

Paper Highways: Proposed US Route 66 Alternate to Las Vegas, Nevada

During February 1956 the State of Nevada in concurrence with the States of California and Arizona submitted a request to the American Association of State Highway Officials to establish US Route 66 Alternate to Las Vegas.  The proposed US Route 66 Alternate would have originated from mainline US Route 66 in Kingman Arizona and followed a multiplex of US Routes 93-466 to Las Vegas, Nevada.  From Las Vegas, Nevada the proposed US Route 66 Alternate would have multiplexed US Routes 91-466 back to mainline US Route 66 in Barstow, California.  The request to establish US Route 66 Alternate was denied during June 1956 due to it being completely multiplexed with other US Routes.  This blog will examine the timeline of the US Route 66 Alternate proposal to Las Vegas, Nevada.
