Interstate 225 north
Succeeding diamond interchanges join the initial two miles of Interstate 225 with DTC Boulevard south, Tamarac Street Parkway north and Yosemite Street. A single off-ramp (Exit 2) serves all movements, with the connection to Yosemite Street using a south side service road. Photo taken 11/10/03.
Interstate 225 straddles the Denver and Arapahoe County line northeast along Cherry Creek Dam and Reservoir. Photo taken 02/02/02.
Continuing north along side the earthen dam holding back Cherry Creek Reservoir, Interstate 225 approaches the Aurora city line and a directional cloverleaf interchange (Exit 4) with Colorado 83 (Parker Road). Photo taken 11/10/03.
Construction through spring 2002 added a flyover ramp from SH 83 (Parker Road) north to I-225 south at Exit 4. The freeway was expanded to six lanes from I-25 north to Parker Road as part of the TREX project through 2005. Photo taken 11/10/03.
A two-lane off-ramp (Exit 4) departs from Interstate 225 north for Colorado 83. Colorado 83 leads northwest to Denver and Glendale and south to Parker and Colorado Springs. Photo taken 11/10/03.
Interstate 225 remained with just four lanes between Parker Road (Exit 4) and Mississippi Avenue (Exit 7) until fall of 2014. With auxiliary lanes, the stretch north to Iliff Avenue (Exit 5) is now eight lanes wide. Photo taken 11/10/03.
A six-ramp parclo interchange (Exit 5) joins Interstate 225 with Iliff Avenue east of the Heather Ridge golf course community. Photo taken 11/10/03.
Reassurance marker posted north of Iliff Avenue. Abilene Street accompanies the freeway east along a commercial strip extending north to Colorado 3 (East 6th Avenue). Photo taken 11/10/03.
A diamond interchange (Exit 7) follows with Mississippi Avenue by the Aurora City Center. Photo taken 11/10/03.
Mississippi Avenue constitutes an east-west arterial from SH 83 (Parker Road) in the Windsor community of Denver east to the Tollgate Village development and Alameda Parkway. Photo taken 11/10/03.
Exit 7 expands to three lanes ahead of Mississippi Avenue. The commercial arterial intersects Abilene Street amid several big box stores to the immediate east. Photo taken 11/10/03.
Alameda Avenue and Interstate 255 converge at a hybrid single point urban interchange (SPUI). The interchange is unique in that flyover ramps tie in the southbound ramps with I-225 to the arterial on the east side of the exchange. Photo taken 11/10/03.
I-225 continues by commercialized frontage, passing by the Aurora City Place retail center on the approach to Colorado 30 (Exit 9). Photo taken 11/10/03.
Colorado 30 follows 6th Avenue east 8.8 miles from Havana Street east to Gun Club Road through Aurora. This section of 6th Avenue is discontinuous with the U.S. 6 section of 6th Avenue west of Downtown Denver. Photo taken 11/10/03.
The parclo interchange (Exit 9) with SH 30 was reconfigured to eliminate the loop ramp from 6th Avenue west to I-225 south. The 2017-opened R-Line runs along the east side ramps now. Photo taken 02/02/02.
The next exit along northbound Interstate 225 is with U.S. 40-287 and Business Loop I-70, which follow Colfax Avenue through Aurora. The arterial forms the county line between Arapahoe County and Adams County. Photo taken 11/10/03.
Interstate 225 crosses Toll Gate Creek one half mile south of the diamond interchange (Exit 10) with Colfax Avenue (U.S. 40-287). Signs for Colfax Avenue omit Business Loop I-70 in both directions of I-225. Photo taken 11/10/03.
Exit 10 was renumbered to Exit 10A in 2012, reflecting the new ramp with 17th Place (Exit 10B). Business Loop I-70 & U.S. 40-287 line Colfax Avenue east to merge with Interstate 70 in five miles. West from I-225, the commercial boulevard enters Denver at the East Colfax community. U.S. 287 splits with U.S. 40 in 10.7 miles at Federal Boulevard. Photo taken 11/10/03.
Erroneous signs referenced Colfax Avenue as Interstate 70 along the northbound off-ramp from I-225. The east sign was still posted as of 2016. Photo taken 02/02/02.
Motorists taking Exit 10B combine with traffic from Colfax Avenue ahead of a signalized turn onto 17th Place west. 17th Place spans Potomac Street and Toll Gate Creek to link Interstate 225 with Fitzsimons Parkway. Photo taken 08/11/16.
The last confirming marker for Interstate 225 appears as the freeway bends northwestward by the Sable Village and Morris Heights subdivisions. Photo taken 08/11/16.
Three lanes advance north one mile to the separation (Exits 12A/B) for Interstate 70 west to Commerce City and Denver and east to Bennett and Limon. Photo taken 08/11/16.
Pena Boulevard, a limited access connector from Interstate 70 to Denver International Airport (DEN) lies just east of Exit 12B. Photo taken 08/11/16.
An interchange sequence sign stands 0.75 miles south of the semi-directional T interchange with Interstate 70. There are no further exits on I-225 north. Photo taken 08/11/16.
The northbound freeway ascends over Smith Road and Union Pacific Railroad tracks as its expands to four lanes. Interstate 70 runs across the north side of Denver west to Wheat Ridge and Golden. Connections with I-270 west lead motorists north through Commerce City to I-25 north for Thornton and Fort Collins. Photo taken 08/11/16.
A series of projects upgraded the exchange (Exit 12) with Interstate 70 to 1998. Three lanes serve commuters heading west into Denver via I-70 while two lanes turn east toward Denver International Airport (DEN) and the rural drive to Limon and Topeka, Kansas. Photo taken 08/11/16.
Exit 12B merges onto Interstate 70 east ahead of back to back ramps for Chambers Road (Exit 283) and the Pena Boulevard freeway (Exit 284). Photo taken 08/11/16.
