How much has your home town changed (from a highway perspective)?

[JCinSummerfield]

Dexter, MI:

Our exit off I-94 (#167, Baker Rd) is at a point where I-94 is 6 lanes, used to be 4.  Now if they could continue westward with that trend.

I guess I can do the Denver metro.  I moved here (the first time) in 1993, so I'll go from then.

I-25 widened during the T-Rex project
I-25 express lanes added
I-25 exit 191 (No Name) closed and exit 192 (RidgeGate Parkway) built
I-70 (currently) being widened between I-25 and I-225
I-76 completed between I-70 and I-25
I-225 exit changed from I-25 to a right exit instead of left
I-225 to I-25 lanes rerouted so that the Yosemite/DTC Blvd exits stay separate from I-225 to go directly to I-25 North
I-225 had an additional exit at 17th Place added
US36 express lanes added
CO470 extended north of I-70 to US6
E-470 completed from Parker Road (its terminus when I moved here) all the way to I-25
Northwest Parkway built
Peña Boulevard built
CO32 decommisioned
CO33 decommisioned
CO51 decommisioned

I'm sure I'm missing a bunch, but a lot has gone on in the past 28 years.

For Boston as a whole, the main one was the completion of the big dig, which happened when I was very little.

- My suburban hometown, South San Francisco.   New ramps at the Oyster Point Boulevard interchange over the last 20 years, starting with a significant realignment ca. 1993 which removed the old overpass crossing US 101 to Butler Avenue, and shifted it towards Sister Cities Boulevard instead.  Removal of the old SB onramp from Airport Boulevard near Linden Avenue, replaced with a SB flyover from Dubuque Avenue on the east side of the freeway.  Addition of a new southbound onramp in the last decade from Airport Boulevard north of Sister Cities Boulevard.  Addition of a new flyover from SB US 101 to EB Oyster Point.  New sign installation project along US 101 in late 2020-early 2021, in progress.

Proposal (but no construction started yet) out there too for a complete reconfiguration of the South Airport Boulevard/US 101 interchange.

- San Francisco, where I've worked for about 7 years:

Removal of Central Freeway north of Market Street in 2005, realignment of I-280 to feed into King Street/Embarcadero ca. 2000 as part of the Giants' stadium project.  Reconstruction of US 101 in the Presidio to modern Interstate standards as the Presidio Parkway in 2015-2016.  East span Bay Bridge.   Tabling of mid-2010s proposal to demolish 280 north of Cesar Chavez (Army) Street.  Planned carpool lane eventually from Redwood City on US 101 north to the 280 extension.   Recent seismic work on the Alemany Maze (101/280 junction).   Addition of movable concrete barrier on Golden Gate Bridge in 2015.

- Sacramento, where I lived and worked 2007-2014:

Introduction of new highway signage with exit numbers in 2009.  Decommissioning of Business 80 west of Oak Park in 2016.  Reconfiguration of Watt Avenue/US 50 cloverleaf into a parclo ca. 2011.  Widening of I-80 through Natomas (north beltline).  Completion of conversion of Route 275/former US 40 and US 99W in West Sacramento from freeway to short boulevard.  Cosumnes River Boulevard being built between Route 160/I-5 in Freeport and Franklin Boulevard.  Capital Southeast Corridor currently being proposed.

- Davis, where I lived 2003-2007:

Addition of exit numbers in the mid-2000s.   Improved signing of Route 113 along its concurrency with I-80.

Other areas I have been to extensively:

Louisville, Kentucky

- East End Bridge.  Second bridge for I-65 and the changes to the Kennedy Interchange.

Makati, Metro Manila, Philippines

- Completion of Skyway Stage 3 from Buendia Avenue to Paco, Manila (2019) and then to Libis Baesa, Caloocan via Quezon City (2020).  Addition of southbound offramp and northbound onramp from Buendia.  Estrella-Pantaleon Bridge under construction.  Reconfiguration of South Avenue to one-way street northbound towards Ayala Malls Circuit Makati (between 2018 and 2019).   Pasig River Expressway east segment proposed to include an interchange at Circuit Makati. 

Paranaque, Metro Manila, Philippines

- Commencement of construction of C-5 South Link Expressway.  Completion of NAIAX between the Skyway and CAVITEX.

Tarlac, Philippines

Lived in Sacramento and Bay area at various points and I agree with the changes. For Fairfield, CA in recent years i-80 is repaved in Asphalt, widened into 10 lanes, Added carpool lanes and renovated the cordelia interchange to deal with both Bay Area and Sacramento commuter traffic in the past decade.
