I-45 has been named the most dangerous highway in America, with approximately 56.5 fatalities for every 100 miles. The stretch running through Houston and Harris County recorded 45 fatal accidents in just two years. Key danger zones include the section from Tidwell Road to I-610 South Loop (11 miles with 45 fatal crashes and 50 deaths) and from Airtex Drive to West Road. Heavy congestion, high speeds, aggressive lane changes, and ongoing construction create a deadly mix.
I-10 ranks as the fourth deadliest road in the country, with the most dangerous stretch running through Harris County and Houston. Between 2010 and 2016, there were 585 fatal car accidents on this highway. The heavy presence of 18-wheelers and commercial trucks makes crashes on I-10 especially severe or fatal.
The North Loop section at the intersection of I-45 to I-10 has been called the second deadliest highway in Texas. The West Loop interchange at Katy Freeway and Southwest Freeway is considered the deadliest highway interchange in Texas. Rush hour traffic and complex merging patterns contribute to frequent collisions.
