  I-25 S. Nevada Avenue/Tejon Street Interchange
CDOT began reconstructing the I-25 S. Nevada Avenue/Tejon Street interchange in February 2001 as part of the I-25 corridor safety improvements through the Pikes Peak Region. This safety improvement was completed in September 2003.

Project Challenges

The S. Nevada Avenue/Tejon Street interchange at I-25 was an outdated
design that CDOT is in the process of replacing throughout the state.
The original interchange was characterized by a sharply curved on-ramp from
Nevada Avenue to I-25, which produced a dangerous weaving pattern
onto I-25.
Motorists on northbound I-25 who used the Tejon Street exit were forced
to slow down in the through lanes of interstate traffic to safely navigate the
sharply curved off-ramp.
Motorists on southbound I-25 who used the Tejon street exit were faced
with conflicting local traffic movements at Arvada Street.

Project Solutions

CDOT replaced the sharply curved on- and off-ramps with a separated
tight diamond interchange configuration that enhances traffic movements from
I-25 to the local street network as well as improves safety through the
interchange.
Acceleration and deceleration lanes were added on I-25 between
Cimarron Street and the Martin Luther King/U.S. 24 Bypass.
CDOT replaced bridge structures over both Nevada Avenue and
Tejon Streets.

Funding

The cost of the interchange safety improvement project was approximately
$30 million.
