Capitol Blvd and Trosper Road generally consist of four travel lanes and one center turn lane with additional turn lanes at the intersection. There are curb and gutter and sidewalks on both sides (widths vary from 6 to 8 feet). There are no shoulders or bicycle lanes. IT Route 13 provides 15-minute headway service in the corridor. There are large regional traffic movements to/from Capitol Blvd from/to I-5 via Trosper Road. Despite double left turn lanes for northbound Capitol and the southbound I-5 offramp, these heavy volumes create failing levels of congestion with severe delays and long intersection queues. The lack of bike lanes and long crosswalk distances greatly discourage multi-modal users, and the heavy congestion, especially at the Capitol/Trosper intersection, further degrades the viability of multi-modal use. Heavy congestion also increases collisions in the project area.

Project Description
'The project relieves congestion, improves safety and enhances multi-modal use by diverting about 400 northbound left turn movements away from the Capitol/Trosper intersection. The project constructs - A two-lane roundabout at Capitol Boulevard SE and Trosper Road SW. - A two-lane roundabout at the intersection of 6th Avenue/Trosper Road. - A new local street, 6th Avenue, connecting Trosper Road SW and Lee Street SW. - A one-lane roundabout at the ramp terminal on 6th Avenue. - A new local street, Trosper Road SE, extending Trosper Road east of Capitol Boulevard to Linda Street.The project realigns the I-5 northbound off-ramp to terminate at the new 6th Avenue between Trosper Road and Lee Street. The new roundabout at the I-5 ramp terminal at 6th Avenue diverts left turn traffic away from Capitol/Trosper by providing an alternate access to northbound I-5. Linda Street is repurposed for local access only with added commercial parking spaces. The project includes roadway reconstruction, stormwater upgrades to treat and infiltrate untreated runoff, bike lanes, sidewalks, pedestrian buffers, replacement of illumination with LED bulbs, signing, and solar powered pedestrian crossing signals/beacons.
