Description: 

The proposed action (Build Alternative) would extend the six-lane, controlled-access, gradeseparated
183A tolled main lanes from their current terminus approximately 0.4 mile north of Hero
Way to approximately 0.4 mile north of SH 29. The 183A tolled main lanes would be located in the
median between the existing northbound and southbound US 183 four-lane divided roadway. The
existing US 183 four-lane divided roadway within the proposed project limits would serve as
frontage roads north to SH 29, and transition back to the existing, undivided US 183 approximately
1.1 miles north of SH 29. This transition would allow the 183A tolled main lanes to merge with the
proposed non-tolled, four-lane, divided US 183 north of SH 29 and, eventually, with the existing
four-lane, non-divided US 183 at the project’s northern terminus. Project design would include
bridges over the South Fork San Gabriel River and multiple box culverts providing for tributary
streamflow. A paved, 10-foot-wide pedestrian/bicycle shared use path would be provided within
existing right-of-way (ROW) along the west side of the project from Hero Way to the planned Seward
Junction South (approximately 4.6 miles).

The proposed 183A main lanes would include three 12-foot-wide lanes in each direction, with 10-
foot-wide paved shoulders and a 38-foot wide grassy median. The main travel lanes would be tolled

as an extension of the existing 183A Toll currently in place south of Hero Way. As previously noted,
the existing US 183 facility would serve as frontage roads and, along with the existing 183A
frontage roads between Hero Way and US 183 (described in Section 2.1, Existing Facility), would
remain in use as a non-tolled facility. The transition from the 183A main lanes to existing US 183
north of SH 29 would comprise two 12-foot-wide lanes, divided, in each direction, with 10-foot-wide
outside shoulders and 4-foot-wide inside shoulders. The 183A main lanes would be depressed
under SH 29 and elevated over intersections with:
• Seward Junction South (planned facility);
• Whitewing Drive/Larkspur Park Boulevard;
• South Gabriel Drive/Green Valley Drive (South Fork San Gabriel River bridge);
• US 183/Bryson Ridge Trail; and
• San Gabriel Parkway.
The existing main lanes are already elevated over Hero Way. The proposed divided US 183 section
north of SH 29 would have an at-grade intersection at County Road (CR) 213/258 with turnarounds
in each direction. Main lane design speed is 70 mph and ramp design speed is 50 mph.
