F reeway <br /> The principal access to the study area is shown in Figure 21. <br /> 1he area is served directly by three freeways: The Santa Ana (I-b), 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 /> Li study area. This severly 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 1-5 connecting Broadway with Owens Drive and linking with Parker <br /> Street and Lawson Way. <br /> L.. <br /> Interviews with the California Highway Patrol together with <br /> ILJ field observations Indicate that the freeways are relatively free flow <br /> during the off peak periods. I-S is congested in both directions during <br /> Lit 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 /> .u except for the southbound connector to 1-5 in both the AN 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 /> S However, congestion does occur daily at locations outside the study <br /> area. Eastbound Rte 22 backs up from its transition with Rte 65 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-S and Rte 57 during both peak periods. <br /> However, through traffic eastbound on Rte 22 passes this congestion-with <br /> 69
