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.

An update to the I-90 signs gallery link. The gallery has moved to its own site:

Old NY 10 and Goodman Mountain in the Adirondacks

  Old highway alignments come in all shapes and sizes, as well as taking some different forms after their lifespan of serving cars and trucks has ended. In the case of an old alignment of what was NY 10 south of Tupper Lake, New York, part of the old road was turned into part of a hiking trail to go up Goodman Mountain. At one time, the road passed by Goodman Mountain to the east, or Litchfield Mountain as it was known at the time. As the years passed, sometime around 1960, the part of NY 10 north of Speculator became part of NY 30, and remains that way today from Speculator, past Indian Lake and Tupper Lake and up to the Canadian Border. At one time, the highway was realigned to pass the Goodman Mountain to the west, leaving this stretch of road to be mostly forgotten and to be reclaimed by nature. During the summer of 2014, a 1.6 mile long hiking trail was approved the Adirondack Park Agency to be constructed to the summit of the 2,176 foot high Goodman Mountain. For the first 0.9 mi

Oregon State Highway 58

  Also known as the Willamette Highway No. 18, the route of Oregon State Highway 58 (OR 58) stretches some 86 miles between US 97 north of Chemult and I-5 just outside of Eugene, Oregon. A main route between the Willamette Valley region of Oregon with Central Oregon and Crater Lake National Park, the highway follows the Middle Fork Willamette River and Salt Creek for much of its route as it makes its way to and across the Cascades, cresting at 5,138 feet above sea level at Willamette Pass. That is a gain of over 4,500 in elevation from where the highway begins at I-5. The upper reaches of OR 58 are dominated by the principal pinnacle that can sometimes be seen from the highway, Diamond Peak, and three nearby lakes, Crescent, Odell and Waldo (Oregon's second largest lake). OR 58 is chock full of rivers, creeks, mountain views, hot springs and waterfalls within a short distance from the highway. OR 58 was numbered as such by the Oregon State Highway Department in 1940. OR 58 is a del

Siuslaw River Bridge - US 101 in Florence, Oregon

  As the Oregon Coast Highway (US 101) was being completed across the State of Oregon during the 1930s, a number of bridges needed to be built to cross some of the state's finest rivers. In Florence, Oregon , the Siuslaw River Bridge was designed and constructed to help fill in the gaps between different coastal communities. Built in 1936, the Siuslaw River Bridge is a bascule bridge flanked by two reinforced concrete arches that spans across the Siuslaw River. The bridge and the river get their names from the Siuslaw tribal people who make their home along the river valleys of this part of the Oregon Coast. Today, the bridge provides a vital link connecting US 101 and the Central Oregon Coast to points north and south. The total length of the Siuslaw River Bridge is 1,568 feet, stretching across the river. But more specifically, the bridge is made up of a north approach with eight spans of reinforced concrete deck girder totaling 478 feet in length. There is a main span in three
