We opened a new FOURTH freeway lane to traffic on northbound I-5 from Alondra Blvd. to the Orr & Day railroad overhead north of Imperial Highway. At that point, it narrows back down to three lanes. After completion of the Florence Ave. interchange, the northbound fourth lane will be extended closer to I-605. We also opened a fourth lane on southbound I-5 from north of Imperial Highway all the way to the Orange County line near Artesia Blvd. Map below:

 

The contractor completed pouring concrete for the new lanes in the median of I-5 north and south of the Florence Ave. Bridge. Video below from October 1 shows 360 degree pan:

The Florence Ave. on ramp to northbound I-5, and the Florence Ave. off ramp from northbound I-5 will all remain closed until the second half of the Florence Ave. Bridge is complete. This is per request by the cities of Downey and Santa Fe Springs, to minimize traffic congestion until the three additional bridge lanes are provided to handle the increase in vehicles. Construction of the second half of the bridge is underway.
