These inlets are suitable for bicycle traffic and are to be used in ditches, medians and other areas subject to infrequent traffic loadings but are not to be placed in areas subject to any heavy wheel loads. These inlets may be placed in areas subject to occasional pedestrian traffic such as landscaped areas and pavement areas where pedestrians can walk around the inlet.. Inlets subject to minimal debris should be constructed without slots. Where debris is a problem inlets should be constructed with slots. Slotted inlets located within roadway clear zones and areas subject to bicycles and/or pedestrians shall have traversable slots. The traversable slot modification is not adaptable to inlet Type H. Slots may be constructed at either or both ends as shown on plans.. Steel grates are to be used on all inlets where bicycle traffic is anticipated. Steel grates are to be used on all inlets with traversable slots. ither cast iron or steel grates may be used on inlets without slots where bicycle traffic is not anticipated. ither cast iron or steel grates may be used on all inlets with non-traversable slots. Subject to the selection described above, when lternate G grate is specified in the plans, either the steel grate, hot dip galvanized after fabrication, or the cast iron grate may be used, unless the plans stipulate the particular type.. Recommended maimum pipe sizes shown are for concrete pipe. Size for other types of pipe must be checked for fit. 5. ll eposed edges and corners shall be / " chamfer or tooled to / " radius. 7.

5 SIGN NOTS FOR TRVRSL SLOT INLTS (PRTIL) FOR XISTING INLTS. The general purpose of these conversions is to remove the hazard of the protruding inlet top, while not creating a hazard by depressing L the top too deeply.. The corrective procedure depends on the approach ditch grade and isting ast Iron To e Replaced With Steel. isting Steel Reticuline To e Replaced When alled For In The Plans Or s irected y The ngineer. hydraulic requirements of the site. The selection of the appropriate case depends on the relationship between inlet top and ditch elevation, and, on the vertical clearance between the top of the uppermost pipe(s) and the grate. The purpose for the ase conversion is to add the traversable slot to an eisting inlet where top removal, change in grate elevation and ditch transitions are not required. ase will normally be applicable to ditches with flatter grades adjoining the inlet. ase will normally be applicable to ditches with steeper grades adjoining the inlet where build up of the eisting ditch is acceptable. reak ngle Not To ceed ^ ( : 0) ist. itch ottom (o With Slot Shown) (See Plans) onst. onc.
