I <br />Freeway <br />The principal access to the study area is shown in Figure 21. <br />The area is served directly by three freeways: The Santa Ana (I-5), the <br />Garden Grove (Rte 22) and the Orange (Rte 57) and indirectly by a fourth <br />- the Costa Mesa -Newport (Rte 55). Interchanges are provided with the <br />main arteries (Main Street, Grand/Glassell, Chapman and a partial <br />interchange with Bristol/LaVeta). The existence of the I-5/Rte 22/Rte <br />57 interchange creates a "spaghetti bowl" immediately adjacent to the <br />study area. This Beverly limits opportunities for creation of new ramps <br />without substantially reconstructing the existing facilities. The <br />freeways themselves create significant travel barriers and bridge <br />crossings are limited to relatively few locations. The City of Santa <br />Ana and Caltrans have budgeted funds for construction of a new bridge <br />over I-5 connecting Broadway with Owens Drive and linking with Parker <br />Street and Lawson Way. j <br />Interviews with the California Highway Patrol together with <br />field observations -ndicate that the freeways are relatively free flow <br />during the off peak periods. I-5 is congested in both directions during <br />the AM and PM peak periods and is becoming increasingly congested during <br />non -peak periods, especially noontime. Rte 57 is relatively free flow <br />except for the southbound connector to I-5 in both the AM and PM peak <br />periods. Northbound Rte 57 is congested north of the study area during <br />the PM peak period at Ball Road. The Rte 22 Freeway is relatively free <br />flow in the vicinity of the study area throughout most of the day. <br />However, congestion does occur daily at locations outside the study <br />area. Eastbound Rte 22 backs up from its transition with Rte 55 in the <br />morning (for the southbound connection) and during the evening (for the <br />northbound connection). Caltrans recently improved westbound Rte 22 in <br />the vicinity of Bristol/LaVeta. This substantially reduced what was <br />previously one of the most congested exists on eastbound Rte 22 in <br />advance of the transition to I-5 and Rte 57 during both peak periods. <br />, <br />However, through traffic eastbound on Rte 22 passes this congestion with <br />75W213 <br />
