Avoiding impacts to the Medical Arts parking garage will be extremely challenging. The garage was constructed right up to the edge of the existing right-of-way set in the 1950’s and sits atop the retaining walls for the Downtown Connector. Any disturbance to the existing wall will likely result in impacts to the parking garage structure above. Because the structure is built right on top of the existing walls, the proposed abutment construction techniques for the Stitch could not be implemented without directly impacting the parking structure. Construction of the proposed abutments in front of the existing wall may be possible but will likely reduce shoulder widths on the Downtown Connector and leaving sufficient space for maintenance of the proposed cap abutments may not be possible. The construction approach for this location will need to be further evaluated as design progresses but impacts to the parking garage structure may be unavoidable.
